-5x+4(2x+2)=-1

- 5 x + 4 (2 x + 2) = - 1

x = - 3

Solution steps

- 5 x + 4 (2 x + 2) = - 1

Expand

4 (2 x + 2) : 8 x + 8

- 5 x + 8 x + 8 = - 1

Add similar elements:

- 5 x + 8 x = 3 x

3 x + 8 = - 1

Move

8

to the right side

3 x = - 9

Divide both sides by

3

x = - 3

3 (1 - 2 x) = \frac{1}{4} (6 x + 9)

- 4 ∣ 2 w + 6 ∣ = - 32

\frac{2}{5} + \frac{3}{2}

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

x + 6 = - x - 6
