Combining like terms, we end up with. That was the whole point behind multiplying this by negative 5. Let's solve a few more systems of equations using elimination, but in these it won't be kind of a one-step elimination. So it does definitely satisfy that top equation. Gauthmath helper for Chrome. And then 5-- this isn't a minus 5-- this is times negative 5. How would you figure out what x and y are if the equation cancels both out. These aren't in any way kind of have the same coefficient or the negative of their coefficient. And we are left with y is equal to 15/10, is negative 3/2. Change both equations into slope-intercept form and graph to visualize. First we need to subtract p from both-side of the equation. 5x-10y =15 and the bottom equation was 3x - 2y = 3, he recognized that by multiplying both sides of the bottom equation by -5 he could get the "y" terms in each equation to be the same size (10) but opposite in sign... Which equation is correctly rewritten to solve for x seeks. that way if he added the two equations together, he would "ELIMINATE" the "y" term and then he would just have to solve for x. And now, we're ready to do our elimination.
The our equation becomes. Because if this is a positive 10y, it'll cancel out when I add the left-hand sides of this equation. So if I make this a 35, and if I make this a negative 35, then I'm going to be all set.
Does the answer help you? Use the power rule to combine exponents. So let's add the left-hand sides and the right-hand sides. Next, use the negative value of the to find the second solution. He could have just used a 5 instead of a -5, but then he would have had to subtract the equations instead of adding them.
But we're going to use elimination. With this problem, there is no solution. Now, we can start with this top equation and add the same thing to both sides, where that same thing is negative 25, which is also equal to this expression. And let's see, if you divide the numerator and the denominator by 8-- actually you could probably do 16. Let's say we want to eliminate the x's this time. And the reason why I'm doing that is so this becomes a negative 35. And the answer is, we can multiply both of these equations in such a way that maybe we can get one of these terms to cancel out with one of the others. Qx = -r + p. We can rearrange the equation, hence; qx = p - r. Which equation is correctly rewritten to solve for - Gauthmath. Divide both-side of the equation by q. Subtract one on both sides.
Let's do another one. Or I can multiply this by a fraction to make it equal to negative 7. Mye, He used a negative 5 so he could just add the two equations and the 10y and -10y become 0y and eliminate the y. When you subtract equations, you're really performing two steps at once. I could get both of these to 35. Is going to be equal to-- 15 minus 15 is 0. So I can multiply this top equation by 7. And now we can substitute back into either of these equations to figure out what y must be equal to. Which equation is correctly rewritten to solve for x a. b. c. d. So this does indeed satisfy both equations. And what do you get? However, let's substitute this answer back to the original equation to check whether if we will get as an answer. Let's substitute into the second of the original equations, where we had 7x minus 3y is equal to 5.
So we can substitute either into one of these equations, or into one of the original equations.
