Question

Y = 5x − 7 −3x − 2y = −12 solved by substitution please show the work too so i can understand

Answer 1

y=3, x=2

Explanation:

-3x-2(5x-7)=-12 (substitute y=5x-7)

simplify

{-13x+14=-12\}

isolate x for -13x +14=-12: x=2

for y=5x-7 substitute x=2

simplify y=3

sorry i know this is quite lenghty but i hope this helps :) have a nice day !!
