2(-4)+3y=5(-4)-y

2 (- 4) + 3 y = 5 (- 4) - y

y = - 3

Solution steps

2 (- 4) + 3 y = 5 (- 4) - y

Remove parentheses:

(- a) = - a

- 2 \cdot 4 + 3 y = 5 (- 4) - y

Multiply the numbers:

2 \cdot 4 = 8

- 8 + 3 y = 5 (- 4) - y

Remove parentheses:

(- a) = - a

- 8 + 3 y = - 5 \cdot 4 - y

Multiply the numbers:

5 \cdot 4 = 20

- 8 + 3 y = - 20 - y

Move

8

to the right side

3 y = - y - 12

Move

y

to the left side

4 y = - 12

Divide both sides by

4

y = - 3

\frac{x - 10}{9} + \frac{x + 7}{3} = 7

6 x = - 36

- 160 = 6 x - 8 (5 x + 3)

x, y - x = 2 x - \frac{2}{3} y

13 - 2 (5 x - 2) = 27
