Question

A student is trying to solve the set of two equations given below: Equation A: x + z = 6 Equation B: 3x + 2z = 1 Which of the following is a possible step used in eliminating the z-term? Multiply equation A by −2. Multiply equation B by 2. Multiply equation A by 3. Multiply equation B by 3.

Answer 1

A) multiply equation A by -2 so you get -2x - 2z = -12 and then you can add both equations to eliminate z

Answer 2

A is the answer helper to to it before me lol
