Astudent is trying to solve the set of two equations given below: equation a: x + z = 6 equation b: 7x + 8z = 1 which of these is a possible step used in eliminating the z-term? multiply equation b by 8. multiply equation a by 7. multiply equation b by 7. multiply equation a by –8.

Multiplying equation A by -8 would help eliminate the z term, as you could then add the two equations to get -x=-47 or x=47.
