Explain how you would create opposite terms for the x-variable in this system. 3x-6y=-8, -1/4x+4y=6

To create opposite terms for the x-variable, you need to multiply the second equation by a number that will result in the x term becoming –3x. That number would need to be a multiple of the denominator, which is 3. Multiplying the second equation by 9 would create opposite terms for the x-variable.
