Answer:

x = 2, y = 4 (2,4)

Explanation:

Put both the equation in ax + by = c

-3x + y = -2

2x + y = 8

Find x:

Multiply 8 times 1, -2 by 1, 2 times 1, and -3 by 1

8 - (-) 2/2 - (-) 3 = x

10/5

x = 2

Plug x back into equation:

-3(2)+y = -2

y = 4

Answer:

x = 2

Explanation:

3x - 2 = - 2x + 8

→ Add 2x on both sides

5x - 2 = 8

→ Add 2 on both sides

5x = 10

→ Divide both sides by

x = 2
