Question

-3x+7y=-16-9x+5y=16 solve using substitution

Answer 1

Answer: How to Solve

Explanation:

~Steps:

{-3x+7y=-16}

{-9x+5y=16}

~Isolate x for -3x+7y=-16: x= -16-7y / 3

{-9(- -16-7y / 3) +5y=16

~Simplify

{-16y-48=16}

~Isolate y for -16y-48=16: y=-4

x= - -16-7(-4) / 3

- -16-7(-4) / 3= -4

x= -4

~Answer:

x= -4, y=-4
