7x + 2 = 6x + 2 if and only x = 0.

8 + 5y = 18 Therefore, 5y = 10 y = 10/5 y = 2

x=0 y=2

5y - 2 + y + 52 = 6y + 50 - 3y6y + 50 = 9y + 50y = 0

X = -2(13 + y) / 3x = 5y / 4 - 1

7x + 2 = 6x + 2 if and only x = 0.

5y-2y= 3y+2 5y-2y-3y= 2 0y= 2

7x + 2 = 5,6

This cannot be solved for numerical answers. There must be 2 equations if there are 2 variables.
