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

B) subtract 3 times the second equation from 2 times the first equation
