3|y-6|+9=45

3 ∣ y - 6 ∣ + 9 = 45

y = - 6 or y = 18

Solution steps

3 ∣ y - 6 ∣ + 9 = 45

Move

9

to the right side

3 ∣ y - 6 ∣ = 36

Divide both sides by

3

∣ y - 6 ∣ = 12

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

y - 6 = - 12 or y - 6 = 12

y - 6 = - 12 or y - 6 = 12

y = - 6 or y = 18

3 - 2 ∣ 7 x - 7 ∣ = 7

x^{2} - x + 4 = 2

∣ 6 x - 9 ∣ = 3 x - 3

3 ∣ 4 x + 5 ∣ = 51

ln y - x^{2} = 0
