x -5y =11——————equation 1
2x-3y = -4—————equation2
Multiplying equation 1 by 2
So,2x-10y =22 —————equation 3
Subtracting equation 2 and 3
+2x-3y = -4
+2x-10y =+22
- + - Sign change in subtract
___________
7y=-26
y= -26/7
Substitution of y=-26/7 in equation1
x-5y = 11
x - 5 * -26/7 = 11
x -(35-26)/7 =11
X- 9 =11 x 7
X - 9 = 77
X= 86
