2/5 x+3/8 x+2/5 x-84=x

\frac{2}{5} x + \frac{3}{8} x + \frac{2}{5} x - 84 = x

x = 480

Solution steps

\frac{2}{5} x + \frac{3}{8} x + \frac{2}{5} x - 84 = x

Add similar elements:

\frac{2}{5} x + \frac{2}{5} x = 2 \cdot \frac{2}{5} x

2 \cdot \frac{2}{5} x + \frac{3}{8} x - 84 = x

2 \cdot \frac{2}{5} x = \frac{4}{5} x

\frac{4}{5} x + \frac{3}{8} x - 84 = x

Move

84

to the right side

\frac{4}{5} x + \frac{3}{8} x = x + 84

Move

x

to the left side

\frac{7}{40} x = 84

Multiply both sides by

40

7 x = 3360

Divide both sides by

7

x = 480

6 + ∣ 2 x + 1 ∣ = 9

\frac{x ^{- 2}}{x ^{- 8}}

\frac{33}{2} - \frac{33}{2 ( 100 ) ^{2}}

62 5^{- \frac{3}{4}}
