19=15w-4(3w-1)

19 = 15 w - 4 (3 w - 1)

w = 5

Solution steps

19 = 15 w - 4 (3 w - 1)

Switch sides

15 w - 4 (3 w - 1) = 19

Expand

- 4 (3 w - 1) : - 12 w + 4

15 w - 12 w + 4 = 19

Add similar elements:

15 w - 12 w = 3 w

3 w + 4 = 19

Move

4

to the right side

3 w = 15

Divide both sides by

3

w = 5

- 21 = \frac{1}{2} c - 11

\frac{c}{0.2} + 0.9 = 3.9

(2 x - 7) + (4 x + 3) = 112

\frac{x}{3} + 7 = - 5

10 + 5 x = 2 x - 11
