3 x/5+5/2 =4

3 \frac{x}{5} + \frac{5}{2} = 4

x = \frac{5}{2}

Decimal Notation

x = 2.5

Solution steps

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

Move

\frac{5}{2}

to the right side

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

Refine

3 \cdot \frac{x}{5} : \frac{3 x}{5}

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

Multiply both sides by

5

3 x = \frac{15}{2}

Divide both sides by

3

x = \frac{5}{2}

4 (x + 2) = 10 x

- 6 (3 x - 1) = - 5 x - 33

15 = x + 3

x, 7 y - 4 x - 8 = 3 y - 4 x + 12

(0.1 - x) = \frac{8}{5} x
