3(x+8)2-20=28

3 (x + 8) 2 - 20 = 28

x = 0

Solution steps

3 (x + 8) \cdot 2 - 20 = 28

Multiply the numbers:

3 \cdot 2 = 6

6 (x + 8) - 20 = 28

Move

20

to the right side

6 (x + 8) = 48

Divide both sides by

6

x + 8 = 8

Move

8

to the right side

x = 0

\frac{3}{5} + \frac{1}{3}

\frac{2}{3} x - 4 = 12 - 2 x

∣ x - 4 ∣ < 2.5

110 + 0.4 x < 80 + 0.5 x

5 x^{2} + 17 x \leq 12
