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 β1 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 β 5y = β12 by β1 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 β 5y = β12 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 β 5y = β12 by β3 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.
