7 ∣ 3 - 9 x ∣ = 28

x = - \frac{1}{9} or x = \frac{7}{9}

Decimal

x = - 0.11111 \dots, x = 0.77777 \dots

Solution steps

7 ∣ 3 - 9 x ∣ = 28

Divide both sides by

7

∣ 3 - 9 x ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 - 9 x = - 4 or 3 - 9 x = 4

3 - 9 x = - 4 or 3 - 9 x = 4

x = - \frac{1}{9} or x = \frac{7}{9}

250 = ∣ z - 150 ∣

x^{2} - 4 x - 4 + 4 = 2 x

∣ 3 x - 7 ∣ = x + 3

x^{2} + 3 ∣ x - 1 ∣ = 0

∣ 3 x - 2 ∣ + 4 = 10
