Why are there letters in math it is bummy and shouldnt exist(8 votes). And you divide both sides by 8, and we get x is equal to 28 over 8, or you divide the numerator and the denominator by 4. Let's let x equal cost of candy bar-- I was going to do a c and a f for Fruit Roll-Up, but I'll just stick with x and y-- cost of candy bar. And we want to find an x and y value that satisfies both of these equations. The left-hand side-- you're just left with a 4y, because these two guys cancel out-- is equal to-- this is 5 minus 21 over 2. For the first problem... the 4y= -8........ where did the -8 came from? I know three easy steps to solve these type of equations by elimination method: 1- equation must always start with the same variable. Let's use the top one. 5 Practice Applying Systems of Linear Equations - NAME DATE PERIOD 6-5 Practice Applying Systems of Linear Equations Determine the best | Course Hero. Let's say I have the equation, 3x plus 4y is equal to 2. So this satisfies both equations. Since 5-21=-16, we get: 4y = -16/2. Nadia buys 3 candy bars and 4 Fruit Roll-Ups for $2.

35 from both sides, what do we get? 48, and that the cost of a Fruit Roll-Up is equal to $0. On the right-hand side, you're adding 25. After you are done with your steps then you would have to go back into your original equation and plug it in for your letter Y. 6x + 3y = -18 and -3x + 4y = 6? After finding the value of x= ⁷⁄₂, he had: 3x + 4y = ⁵⁄₂. Due to the nature of the mathematics on this site it is best views in landscape mode. We want to fence in a field whose length is twice the width and we have 80 feet of fencing material. So y is equal to $0. The Organization of Petroleum Exporting. So the solution to this equation is x is equal to 7/2, y is equal to negative 2. So let's verify that it also satisfies this bottom equation.
How would i solve this problem?? John and Dave can paint the house in 17 hours working together. Since -16/2 = -8 we get. For -6x+3y=-18, solve for y by adding 6x to both sides, and you get 3y = 6x + 18.
Now you have to convert the other equation, -3x+4y=6. The second statement. So the cost of a Fruit Roll-Up is $0. And you're probably saying, Sal, hold on, how can you just add two equations like that? So you get 8x is equal to 28. We just chose letters to represent the unknown. I'm making this messy. When I looked at these two equations, I said, oh, I have a 4y, I have a negative 4y. We know that 5x minus 4y is 25. Peter also buys 3 candy bars, but could only afford 1 additional Fruit Roll-Up.
Divide both sides by 4, and you get y is equal to negative 2. So you divide both sides. You could solve this using any of the techniques we've seen so far-- substitution, elimination, even graphing, although it's kind of hard to eyeball things with the graphing. So let's subtract 3x plus y from the left-hand side of the equation. And we could substitute this back into either of these two equations.
