-5+6|2x+2|=7

- 5 + 6 ∣ 2 x + 2 ∣ = 7

x = - 2 or x = 0

Solution steps

- 5 + 6 ∣ 2 x + 2 ∣ = 7

Move

5

to the right side

6 ∣ 2 x + 2 ∣ = 12

Divide both sides by

6

∣ 2 x + 2 ∣ = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 2 = - 2 or 2 x + 2 = 2

2 x + 2 = - 2 or 2 x + 2 = 2

x = - 2 or x = 0

x + 4 = 5

\frac{ln ( \frac{1}{2} )}{1620}

177147 = 54 ln (3) (2) + b

- 6 x + 5 x = - 4

- 3 (p - 7) \geq 21
