|(2x-7)/5 |=7

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

x = - 14 or x = 21

Solution steps

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

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

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

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

x = - 14 or x = 21

4 x^{2} + 2 x - 2 = 1

x^{4} + 4 x^{2} - 12

x y + 4 y - 8 x - 32

- (4)^{- 2}

- 4 (2 x - 4) - 2 x - 2 = - 36
