Question

Solve by substitution 2x-3y+8=0;x-4y+7=0

Answer 1

Answer:

2x-3y=-8

2x+8=3y

(2x+8)/3=y

put this value of y in equation x-4y=7

on solving the equation you'll get the value of x i.e.-53/5

then put the value of x in equation (2x+8)/3=y you'll be getting the value of y..i.e.-66/5.......
