5|2x-1|=25

5 ∣ 2 x - 1 ∣ = 25

x = - 2 or x = 3

Solution steps

5 ∣ 2 x - 1 ∣ = 25

Divide both sides by

5

∣ 2 x - 1 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x - 1 = - 5 or 2 x - 1 = 5

2 x - 1 = - 5 or 2 x - 1 = 5

x = - 2 or x = 3

x^{2} - 37 = - 13

- 2 (5 x + 1) > 48

\frac{147 π}{180} - \frac{5 π}{6}

\frac{15 x ^{4} y ^{2} z}{- 3 x y ^{6} z ^{3}}

14 x^{2} + 7 x - 21
