Question

Solve the system of equations x – 3y = 1 and 2x + 2y = 18 by combining the equations.

Answer 1

Step-by-step explanation:

1) 2x + x = 3x

2) 3y - 2y = y

3) 18 + 1 = 19

4) 3x + y = 19

5) y + -1y = 0

6) Divide each side by '3'.

x = 6.333333333 + -0.3333333333y

7) x = 6.333333333 + -0.3333333333y
