0.4x-0.2(x+20)=0.4(20)

0.4 x - 0.2 (x + 20) = 0.4 (20)

x = 60

Solution steps

0.4 x - 0.2 (x + 20) = 0.4 (20)

Remove parentheses:

(a) = a

0.4 x - 0.2 (x + 20) = 0.4 \cdot 20

Multiply the numbers:

0.4 \cdot 20 = 8

0.4 x - 0.2 (x + 20) = 8

Multiply both sides by

10

4 x - 2 (x + 20) = 80

Expand

- 2 (x + 20) : - 2 x - 40

4 x - 2 x - 40 = 80

Add similar elements:

4 x - 2 x = 2 x

2 x - 40 = 80

Move

40

to the right side

2 x = 120

Divide both sides by

2

x = 60

\frac{x + 3}{4} = 5

5 (x + 3) = 3 (x + 5)

3 x + 5 = 5 x - 57

3 y = - 15

\frac{2}{5} n + 6 = 10
