2 x + 5 + 2 x + 3 x = 2 x + 9

x = \frac{4}{5}

Decimal Notation

x = 0.8

Solution steps

2 x + 5 + 2 x + 3 x = 2 x + 9

Subtract

2 x

from both sides

2 x + 5 + 2 x + 3 x - 2 x = 2 x + 9 - 2 x

Simplify

5 + 2 x + 3 x = 9

Add similar elements:

2 x + 3 x = 5 x

5 + 5 x = 9

Move

5

to the right side

5 x = 4

Divide both sides by

5

x = \frac{4}{5}

3 x^{2} + 23 x + 14

2 (6 + 4 n) \geq 12 - 8 n

- \frac{1}{3} x^{2} - 1 = 29

z^{2} - 8 z = 0

\frac{1}{2} ∣ x ∣ - 4 = 4
