0.8=2(-x-4.2)-5

0.8 = 2 (- x - 4.2) - 5

x = - 7.1

Solution steps

0.8 = 2 (- x - 4.2) - 5

Switch sides

2 (- x - 4.2) - 5 = 0.8

Move

5

to the right side

2 (- x - 4.2) = 5.8

Divide both sides by

2

- x - 4.2 = 2.9

Move

4.2

to the right side

- x = 7.1

Divide both sides by

- 1

x = - 7.1

x + 10 = 3 (x - 6)

(3 x - 2) 2 - 2 (x - 5) + 3 = 3 - (1 - 2 x) + 6 x

12 - 12 x = - 6 x + 48

\frac{2 x}{3} - 1 = \frac{x}{3} + 4

2 x - \frac{x + 3}{5} = - 1 \frac{1}{2}
