1-2|8+4x|=-7

1 - 2 ∣ 8 + 4 x ∣ = - 7

x = - 3 or x = - 1

Solution steps

1 - 2 ∣ 8 + 4 x ∣ = - 7

Move

1

to the right side

- 2 ∣ 8 + 4 x ∣ = - 8

Divide both sides by

- 2

∣ 8 + 4 x ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 + 4 x = - 4 or 8 + 4 x = 4

8 + 4 x = - 4 or 8 + 4 x = 4

x = - 3 or x = - 1

4 x^{2} - 16 x + 9 = 0

\frac{4 ( 0.36 )}{20 ( 1 - 7 e ^{- 6} )}

(5 x^{5})^{2}

3 = \frac{g}{4} - 5
