4|t+3|=16

4 ∣ t + 3 ∣ = 16

t = - 7 or t = 1

Solution steps

4 ∣ t + 3 ∣ = 16

Divide both sides by

4

∣ t + 3 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

t + 3 = - 4 or t + 3 = 4

t + 3 = - 4 or t + 3 = 4

t = - 7 or t = 1

\frac{1}{4} (5)^{2}

2 x^{3} - 4 x^{2} - 14 x + 28

2 f - 9 = 14 f + 1

2 x - 2

\frac{3}{4} x^{2} + \frac{4}{5} x = 0
