|2x-2|-6=-2

∣ 2 x - 2 ∣ - 6 = - 2

x = - 1 or x = 3

Solution steps

∣ 2 x - 2 ∣ - 6 = - 2

Move

6

to the right side

∣ 2 x - 2 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

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

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

x = - 1 or x = 3

\frac{\frac{2}{3} - \frac{1}{5}}{\frac{7}{2} - \frac{5}{6}}

r^{2} - r - 12

- 6 x - 10 = - 3 x - 4 - 18

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

4 x^{2} - 2 x = 0
