To solve this system of equations by elimination, what operation could be used to eliminate the y-variable and find the value of x? 2x − 4y = 6 −3x + 3y = 12

x = -11

Step-by-step explanation:

The given system of the equations is

2x - 4y = 6 -------(1)

-3x + 3y = 12 --------(2)

To eliminate the variable y, multiply equation 1 by 3 and multiply equation 2 by 4 and add them

3(2x - 4y) + 4(-3x + 3y) = 6×3 + 12×4

6x - 12y - 12x + 12y = 18 + 48

-6x = 66

x = -

x = -11

Therefore, value of x is (-11).
