Plese .a student is trying to solve the set of two equations given below: equation a: x + z = 6 equation b: 2x + 3z = 1 which of the following is a possible step used in eliminating the z-term? multiply equation b by 3. multiply equation a by 2. multiply equation b by 2. multiply equation a by −3.

D. Multiply equation A by −3.

Step-by-step explanation:

We have been given a system of equations.

Equation A:

Equation B:

We are asked to determine the possible step used in eliminating the z-term.

We can see that coefficient of z term is  equation B is 3, so eliminate z term from the both equations the coefficient of z term is equation A should be .

We can make coefficient of z term to in equation A by multiplying equation A by that will give us:

Now, adding equation A and equation B the z term will get eliminated.

Therefore, option D is the correct choice.

step-by-step explanation:
