0.2x-0.5=0.1x+7

0.2 x - 0.5 = 0.1 x + 7

x = 75

Solution steps

0.2 x - 0.5 = 0.1 x + 7

Multiply both sides by

10

2 x - 5 = x + 70

Move

5

to the right side

2 x = x + 75

Move

x

to the left side

x = 75

8 x^{2} = 8 x + 1

\frac{x}{4} = - \frac{20}{16}

\frac{1 - 5 x}{2 - x} < 4

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

(x + 1) (x + 4) = 28
