Question

solve by the substitution method.
8x+3y=-40
x=48-7y
THE ANSWER SHOULD BE AN ORDERED PAIR. PLEASE HELP ASAP

Answer 1

First you need to replace the x in the original equation with the given variable 48-7y
8(48-7y) + 3y = -40
384 -56y +3y=-40

-56y + 3y = -40 - 384
-53y = -424
-53y/-53=-424/-53
y=8 x=-8

Ordered pair (8,-8)

Answer 2

sorry, I typed ordered pair wrong, the ordered pair is (-8, 8)
