solvefor y,-2|2y-1|-5=-7

solve for

y, - 2 ∣ 2 y - 1 ∣ - 5 = - 7

y = 0 or y = 1

Solution steps

- 2 ∣ 2 y - 1 ∣ - 5 = - 7

Move

5

to the right side

- 2 ∣ 2 y - 1 ∣ = - 2

Divide both sides by

- 2

∣ 2 y - 1 ∣ = 1

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 y - 1 = - 1 or 2 y - 1 = 1

2 y - 1 = - 1 or 2 y - 1 = 1

y = 0 or y = 1

x^{2} - 100 = 99

x^{2} - 22 x + 2 = 18

∣ 5 x + 1 ∣ = 5

2 ∣ x - 1 ∣ - 8 = 6

u, ∣ 2 u + 14 ∣ = - 6
