x = - \frac{7}{4} or x = \frac{11}{4}

Decimal

x = - 1.75, x = 2.75

Solution steps

∣ 4 x - 2 ∣ = 9

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

4 x - 2 = - 9 or 4 x - 2 = 9

4 x - 2 = - 9 or 4 x - 2 = 9

x = - \frac{7}{4} or x = \frac{11}{4}

∣ r ∣ = 15

2 ∣ 1 x + 1 ∣ - 13 = 0

d, ∣ d + 2 ∣ + 7 = 7

∣ u + 1 ∣ = 2
