From (1), write it as:
Substitute x in (3) into (2)
Expand the left hand side
-21y-5y = 34 + 70
-26y = 104
y=104/-26 = -4 .....(5)
Now substitute (5) into (3) to find x.
After that, substitute the values of x and y into equations (1) and (2) to verify if the solutions are correct.
this is your y value now just plug this value back into the x to find your x value
hope this helped.
