\frac{2}{5} x - \frac{1}{10} = \frac{3}{4} x

x = - \frac{2}{7}

Decimal Notation

x = - 0.28571 \dots

Solution steps

\frac{2}{5} x - \frac{1}{10} = \frac{3}{4} x

Move

\frac{1}{10}

to the right side

\frac{2}{5} x = \frac{3}{4} x + \frac{1}{10}

Move

\frac{3}{4} x

to the left side

- \frac{7}{20} x = \frac{1}{10}

Multiply both sides by

20

- 7 x = 2

Divide both sides by

- 7

x = - \frac{2}{7}

- 8 + 8 x = - 5 + 3 (3 x + 4)

2 x + 2 = 6 x - 6

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

x, 3 x + y = 26

x, \frac{d ^{2} y}{d t ^{2}} + 15 y = 2 x
