\frac{2}{5} x = 4 x - 12

x = \frac{10}{3}

Decimal Notation

x = 3.33333 \dots

Solution steps

\frac{2}{5} x = 4 x - 12

Move

4 x

to the left side

- \frac{18}{5} x = - 12

Multiply both sides by

5

- 18 x = - 60

Divide both sides by

- 18

x = \frac{10}{3}

∣ x + 6 ∣ \leq 4

- 0.25 x^{2} + 177.5 x = 57.5 x + 14400

\frac{2 ( x + 1 )}{6} = 3 x - 5

\frac{7 ^{2}}{7 ^{- 2}}

7 x - 2 = 4 x + 3
