5 ∣ 3 + 7 m ∣ + 1 = 51

m = - \frac{13}{7} or m = 1

Solution steps

5 ∣ 3 + 7 m ∣ + 1 = 51

Move

1

to the right side

5 ∣ 3 + 7 m ∣ = 50

Divide both sides by

5

∣ 3 + 7 m ∣ = 10

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 + 7 m = - 10 or 3 + 7 m = 10

3 + 7 m = - 10 or 3 + 7 m = 10

m = - \frac{13}{7} or m = 1

(10 n)^{\frac{3}{2}}

\frac{x}{5} > 30

\frac{2}{3} + \frac{2}{4}

x^{- 2}

4 x - 2 x^{2} = - \frac{32}{3}
