-12=2+5x+2x

- 12 = 2 + 5 x + 2 x

x = - 2

Solution steps

- 12 = 2 + 5 x + 2 x

Switch sides

2 + 5 x + 2 x = - 12

Add similar elements:

5 x + 2 x = 7 x

2 + 7 x = - 12

Move

2

to the right side

7 x = - 14

Divide both sides by

7

x = - 2

3 (2 x - 1) - 2 = 2 (x + 7) + 1

\frac{2}{7} x - \frac{9}{4} = \frac{5}{3}

x, 2 x - 7 y = 13

x, 2 x - 7 y = 17

9 a + 7 = 25
