6 + 3 ∣ 2 x + 7 ∣ = 30

x = - \frac{15}{2} or x = \frac{1}{2}

Solution steps

6 + 3 ∣ 2 x + 7 ∣ = 30

Move

6

to the right side

3 ∣ 2 x + 7 ∣ = 24

Divide both sides by

3

∣ 2 x + 7 ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 7 = - 8 or 2 x + 7 = 8

2 x + 7 = - 8 or 2 x + 7 = 8

x = - \frac{15}{2} or x = \frac{1}{2}

\frac{8}{9} + 1

\frac{( n + 1 ) !}{( n + 2 ) !}

- \frac{2}{3} a + \frac{5}{6} a - \frac{1}{6}

- 3 - (a - 2) = 7 a + 15
