- 3 ∣ 2 + 4 x ∣ - 7 = - 43

x = - \frac{7}{2} or x = \frac{5}{2}

Decimal Notation

x = - 3.5, x = 2.5

Solution steps

- 3 ∣ 2 + 4 x ∣ - 7 = - 43

Move

7

to the right side

- 3 ∣ 2 + 4 x ∣ = - 36

Divide both sides by

- 3

∣ 2 + 4 x ∣ = 12

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 + 4 x = - 12 or 2 + 4 x = 12

2 + 4 x = - 12 or 2 + 4 x = 12

x = - \frac{7}{2} or x = \frac{5}{2}

(5 - 2 i^{2})^{2}

\frac{315}{5}

2 (\frac{4 y ^{2} + 41}{5}) + 3 y^{2} = 21

25 x^{2} + 10 x - 6 = 0

(- 4)^{2}
