(0.3)(3+2x)+1.2x=3.2

(0.3) (3 + 2 x) + 1.2 x = 3.2

x = \frac{23}{18}

Decimal Notation

x = 1.27777 \dots

Solution steps

(0.3) (3 + 2 x) + 1.2 x = 3.2

0.3 (3 + 2 x) + 1.2 x = 3.2

Multiply both sides by

10

3 (3 + 2 x) + 12 x = 32

Expand

3 (3 + 2 x) : 9 + 6 x

9 + 6 x + 12 x = 32

Add similar elements:

6 x + 12 x = 18 x

9 + 18 x = 32

Move

9

to the right side

18 x = 23

Divide both sides by

18

x = \frac{23}{18}

3 (x + 12) = 8 - 4 x

x, y - 4 = 3 (x - 1)

7 x - 3 x = 5 x + 2

3 (x + a + b) = 2 (x + 2 a + b)

x, 2 x - 3 y = - 7
