Question

Solve the system of linear equations.
x = 8 - 2y
x + 3y = 12

Answer 1

(0,4)

Explanation:

x = 8 - 2y

x + 3y = 12

Substitute the first equation into the second equation

x+3y =12

(8-2y) +3y = 12

Combine like terms

8+y = 12

Subtract 8 from each side

8+y-8 = 12-8

y = 4

Now we need to solve for x

x = 8 -2y

= 8-2(4)

= 8-8

=0

(0,4)
