(\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

Expand

(\frac{2}{5}) x : \frac{2}{5} x

\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^{4} - 4 x^{2}

4 y^{2} = 80

b + 1 = \frac{b}{2}

(\frac{4 b ^{3}}{c})^{2}
