2(5x)/7 =3

2 \frac{5 x}{7} = 3

x = \frac{21}{10}

Decimal Notation

x = 2.1

Solution steps

2 \cdot \frac{5 x}{7} = 3

Refine

2 \cdot \frac{5 x}{7} : \frac{10 x}{7}

\frac{10 x}{7} = 3

Multiply both sides by

7

10 x = 21

Divide both sides by

10

x = \frac{21}{10}

x^{2} - 32 x + 256 = 0

0.75 x = 9

(5 x^{4} y^{3})^{2}

\frac{3}{5} - \frac{1}{2}

2 - 2 ∣ x - 2 ∣ = - 8
