0.4(2-q)=0.2(q+7)

0.4 (2 - q) = 0.2 (q + 7)

q = - 1

Solution steps

0.4 (2 - q) = 0.2 (q + 7)

Multiply both sides by

10

4 (2 - q) = 2 (q + 7)

Expand

4 (2 - q) : 8 - 4 q

Expand

2 (q + 7) : 2 q + 14

8 - 4 q = 2 q + 14

Move

8

to the right side

- 4 q = 2 q + 6

Move

2 q

to the left side

- 6 q = 6

Divide both sides by

- 6

q = - 1

x, 2 y - x = 6

\frac{1}{5} x + 8 = \frac{1}{10} x + 9

23 x - 15 x = x - 1

w + 14 = 10

f, (f \cdot g) (x) = (x^{2} - 3 x + 2) (x - 1)
