solve system of equations

1 Answer

The system of equations are

y = - 3x + 4------------ > (1)

x + 4y = - 6 ------------> (2)

Substitute Eq(!) in Eq (2)

x + 4(-3x + 4) = - 6

x - 12x + 16 = - 6

- 11x + 16 = - 6

- 11x = - 6 - 16

- 11x = - 22

11x = 22

x = 22/11

x = 2

Substitute x = 2 in Eq (1)

y = - 3(2) + 4

y = - 6 + 4

y = - 2

Answer :

The Solutions are x = 2 and y = - 2.
