x = - 2 or x = \frac{10}{7}

Decimal Notation

x = - 2, x = 1.42857 \dots

Solution steps

∣ 7 x + 2 ∣ = 12

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 x + 2 = - 12 or 7 x + 2 = 12

7 x + 2 = - 12 or 7 x + 2 = 12

x = - 2 or x = \frac{10}{7}

5 x^{2} + 7 x - 12 = 0

2 h > 8

\frac{x}{4} - 17 = 18

(2 x - 3) (x + 4) = 0

3 x^{2} + 2 x - 7 = 0
