3|x-4|+1=19

3 ∣ x - 4 ∣ + 1 = 19

x = - 2 or x = 10

Solution steps

3 ∣ x - 4 ∣ + 1 = 19

Move

1

to the right side

3 ∣ x - 4 ∣ = 18

Divide both sides by

3

∣ x - 4 ∣ = 6

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x - 4 = - 6 or x - 4 = 6

x - 4 = - 6 or x - 4 = 6

x = - 2 or x = 10

\frac{x + 1}{x - 1} < 1

3 5^{2} + b^{2} = 3 7^{2}

5 x^{2} + 17 x - 40

10 x^{2} + 11 x = 0

m^{2} + 2 mn + n^{2}
