Step-by-step explanation:
2x - 3y + 8 = 0
x - 4y +7 =0
2x - 3y = -8 --------------------1
x - 4y = -7 ----------------------2
multiplying eqation 1 by 1 and equation 2 by 2
2x - 3y = -8
2x- 8y = -14
subtracting
5y = 6
y = 6/5
putting the value of y in equation 1
2x - 3(6/5) =-8
2x =-8 -18/5
2x = -22/5
x = -22/5*2
x = -11/5
