3(7+2a)+2a=33

3 (7 + 2 a) + 2 a = 33

a = \frac{3}{2}

Decimal Notation

a = 1.5

Solution steps

3 (7 + 2 a) + 2 a = 33

Expand

3 (7 + 2 a) : 21 + 6 a

21 + 6 a + 2 a = 33

Add similar elements:

6 a + 2 a = 8 a

21 + 8 a = 33

Move

21

to the right side

8 a = 12

Divide both sides by

8

a = \frac{3}{2}

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

2 x + 3 x - 11 = 14

3.9 = \frac{x}{8}

12 x + 3 (2 x - 4) = 60

3 = \frac{p}{- 5} + 1
