-2(-5x-6)=3x+15

- 2 (- 5 x - 6) = 3 x + 15

x = \frac{3}{7}

Solution steps

- 2 (- 5 x - 6) = 3 x + 15

Expand

- 2 (- 5 x - 6) : 10 x + 12

10 x + 12 = 3 x + 15

Move

12

to the right side

10 x = 3 x + 3

Move

3 x

to the left side

7 x = 3

Divide both sides by

7

x = \frac{3}{7}

6 x + 8 = 7 x + 77 x + 7

7 b - 20 = 3 b + 12

0.5 x + 3 = 0.4 x + 3.3

- 147 = - 3 (6 n + 2) + 3

15 - 5 b = 6 b + 4 b
