9+4|3-5x|=21

9 + 4 ∣ 3 - 5 x ∣ = 21

x = 0 or x = \frac{6}{5}

Solution steps

9 + 4 ∣ 3 - 5 x ∣ = 21

Move

9

to the right side

4 ∣ 3 - 5 x ∣ = 12

Divide both sides by

4

∣ 3 - 5 x ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 - 5 x = - 3 or 3 - 5 x = 3

3 - 5 x = - 3 or 3 - 5 x = 3

x = 0 or x = \frac{6}{5}

2 - x^{2} = 0

75 r^{2} + 90 r f + 27 f^{2}

8 (12 - k) = 3 (k + 21)

32 \geq - 16 p

(\frac{1}{3})^{2} + y^{2} = 1
