Solve the system of equations.
- 4x + 11y = 15
2 = 2y

y = 1

x = -1

Step-by-step explanation:

- 4x + 11y = 15

2 = 2y

Find y from the second equation

2 = 2y

2/2 = 2y/2

1 = y

Substitute y into the first equation.

- 4x + 11y = 15

- 4x + 11(1) = 15

- 4x + 11 = 15

-4x = 15 - 11

-4x/-4 = 4/-4

x = -1
