5|2x-1|+3=28

5 ∣ 2 x - 1 ∣ + 3 = 28

x = - 2 or x = 3

Solution steps

5 ∣ 2 x - 1 ∣ + 3 = 28

Move

3

to the right side

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

3 x - 5 + 2 x = 25

(\frac{1 0 ^{6}}{4 ^{6}})^{- \frac{1}{6}}

n^{2} - 46 n + 88

1 - a^{2} b^{4}

3 x^{2} - 7 x + 14 \geq 10
