2/5 (7x-1)=3x-1

\frac{2}{5} (7 x - 1) = 3 x - 1

x = 3

Solution steps

\frac{2}{5} (7 x - 1) = 3 x - 1

Expand

\frac{2}{5} (7 x - 1) : \frac{14}{5} x - \frac{2}{5}

\frac{14}{5} x - \frac{2}{5} = 3 x - 1

Move

\frac{2}{5}

to the right side

\frac{14}{5} x = 3 x - \frac{3}{5}

Move

3 x

to the left side

- \frac{1}{5} x = - \frac{3}{5}

Multiply both sides by

- 5

x = 3

4 (x - 3) = 5

m^{4} + 8 m^{2} + 12

36 + 5 x - x^{2}

\frac{y}{- 3} = \frac{1}{6}

∣ 4 x - 7 ∣ = 0
