∣ 7 - 5 x ∣ = 5

x = \frac{2}{5} or x = \frac{12}{5}

Solution steps

∣ 7 - 5 x ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 - 5 x = - 5 or 7 - 5 x = 5

7 - 5 x = - 5 or 7 - 5 x = 5

x = \frac{2}{5} or x = \frac{12}{5}

v + \frac{3}{4} \leq \frac{3}{8}

0 \geq 5 k + 15

7 x^{2} - 14 x = - 7

∣ x + 5 ∣ \leq 3

n^{2} + 4 = 40
