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

x = - \frac{18}{5}

Decimal Notation

x = - 3.6

Solution steps

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

Move

5

to the right side

\frac{x}{2} = 3 x + 9

Multiply both sides by

2

x = 6 x + 18

Move

6 x

to the left side

- 5 x = 18

Divide both sides by

- 5

x = - \frac{18}{5}

1 - \frac{1}{2}

1 + x^{2} + y^{2} + x^{2} y^{2}

- 8 < 3 x - 9 < 12

(\frac{x}{y})^{2}

2 x < 4 x - 6 \leq 20
