Find the solutions for the following systems of equations

1 Answer

The system of equations are

4y = −7(x + 4) ---------------> (1)

4y = x + 4 -------------------> (2)

Equate equations (1) and (2)

−7(x + 4) = x + 4

−7x - 28 = x + 4

−7x - x = 28 + 4

−8x = 32

8x = - 32

x = (-32)/8

x = - 4

Substitute x = -4 in Eq (2)

4y = -4 + 4

4y = 0

y = 0

Answer :

The solutions are x = -4 and y = 0.
