-0.45(20)+0.6x=0.3(20+x)

- 0.45 (20) + 0.6 x = 0.3 (20 + x)

x = 50

Solution steps

- 0.45 (20) + 0.6 x = 0.3 (20 + x)

Remove parentheses:

(a) = a

- 0.45 \cdot 20 + 0.6 x = 0.3 (20 + x)

Multiply the numbers:

0.45 \cdot 20 = 9

- 9 + 0.6 x = 0.3 (20 + x)

Multiply both sides by

10

- 90 + 6 x = 3 (20 + x)

Expand

3 (20 + x) : 60 + 3 x

- 90 + 6 x = 60 + 3 x

Move

90

to the right side

6 x = 3 x + 150

Move

3 x

to the left side

3 x = 150

Divide both sides by

3

x = 50

\frac{( x - 1 )}{3} + \frac{( 2 x + 1 )}{5} = \frac{( 3 x - 1 )}{4}

x, y - 5 = 3 (x + 2)

k - 8 = - 8

y, 3 y + \frac{x}{2} - 4 = 8

x, y - 5 = 3 (x - 5)
