x-9/10 =7x+1/2

x - \frac{9}{10} = 7 x + \frac{1}{2}

x = - \frac{7}{30}

Decimal Notation

x = - 0.23333 \dots

Solution steps

x - \frac{9}{10} = 7 x + \frac{1}{2}

Move

\frac{9}{10}

to the right side

x = 7 x + \frac{7}{5}

Move

7 x

to the left side

- 6 x = \frac{7}{5}

Divide both sides by

- 6

x = - \frac{7}{30}

x^{2} + 10 x - 15 = 0

∣ 1 + 6 n ∣ < 23

∣ 2 x + 6 ∣ = ∣ x - 2 ∣

\frac{5 x}{2} - x = \frac{x}{6} - \frac{16}{3}

(x + 1) (x + 2) \leq 9
