2x+3y=4

and

2x-5y=-12

solve the given system by elimination and justify each step. which procedure would not result in a system with a pair of opposite terms?

a) multiply both sides of 2x + 3y = 4 by −1 and use the other equation to produce a system with a pair of opposite terms. this is an application of the multiplicative property of equality.

b) multiply both sides of 2x − 5y = −12 by −1 and use the other equation to produce a system with a pair of opposite terms. this is an application of the multiplicative property of equality.

c) multiply both sides of 2x − 5y = −12 by 3 and multiply both sides of 2x + 3y = 4 by 5 to produce a system with a pair of opposite terms. this is an application of the multiplicative property of equality.

d) multiply both sides of 2x − 5y = −12 by −3 and multiply both sides of 2x + 3y = 4 by 5 to produce a system with a pair of opposite terms. this is an application of the multiplicative property of equality.
