Solve the system of equations -x + 4y = 6 and 4x – 8y = 0 by combining the equations.

(- x +4y =6)
(4x -8y =0)

-x + 4y = 6
4x - 8y = 0

Answer:

x=6 y=3

Step-by-step explanation:

Isolate x for -x+ 4y = 6: x= -6+ 4y

Substitute x = -6 + 4y

4(-6+ 4y) - 8y = 0

Simplify

-24+ 8y =0

Isolate y for -24 + 8y = 0: y =3

For x = -6+ 4y

Substitute y =3

X= -6+ 4 × 3

Simplify

X=6

The solutions to the system of equations are:

x=6 y=3
