Question

Solve for the system of equations :

x-2y=6
y=11-3x

Answer 1

x=4 y = -1

Explanation:

x-2y=6 ->

-2y=6-x ->

y= 6-x/-2 ->

y= 1/2x-3 .

since both equations are equal to y,

they are equal to each other.

11-3x = 1/2x-3 ->

14 = 3 1/2x ->

14=7/2x ->

x=4 ->

put 4 in the original equation ->

y = 11-12 -> -1
