Question

Solve the system of equations.
12x-5y=-20
y=x+4

Answer 1

x = 0, y = 4

Explanation:

12x - 5y = 20

y = x+4

____________

12x - 5y = 20

-x + y = 4

___________

12x - 5y = 20

5(-x+y = 4)

___________

12x - 5y = 20

-5x + 5y = 20

____________

7x = 0

x = 0

y = x + 4

y = 0+4

y = 4
