You have the following system of equations:

-10x - 4y = -18

x = y

In order to solve the previous equation, replace x = y into the first equation, and solve for y, just as follow:

.10(y) - 4y = -18

-10y - 4y = -18 simplify left side

-14y = -18 divide by -14 both sides

y = 18/14

consider x = y:

x = y = 18/14
