To solve this system of equations by elimination, what operation would be used to elimate the y variable and find the value of x

6x+5y=2
4x+2y=8

You would need to multiply the bottom equation by -2.5 (negative 2.5)

6x+5y=2

4x+2y=8

Multiply the bottom equation by -2.5:

-10x - 5y = -20

Now you can add the top equation to the new equation and it eliminates the Y variable:

6x + 5y = 2 +

-10x -5y = -20

Becomes:

-4x = -18

To find x, divide both sides by -4:

x = -18 / -4

x = 4.5

the answer is 489
