9x+(-2)x+8=3x+5-6x-(-5)x-18

9 x + (- 2) x + 8 = 3 x + 5 - 6 x - (- 5) x - 18

x = - \frac{21}{5}

Decimal Notation

x = - 4.2

Solution steps

9 x + (- 2) x + 8 = 3 x + 5 - 6 x - (- 5) x - 18

Remove parentheses:

(- a) = - a

9 x - 2 x + 8 = 3 x + 5 - 6 x - (- 5) x - 18

Add similar elements:

9 x - 2 x = 7 x

7 x + 8 = 3 x + 5 - 6 x - (- 5) x - 18

Apply rule

- (- a) = a

7 x + 8 = 3 x + 5 - 6 x + 5 x - 18

Group like terms

7 x + 8 = 3 x - 6 x + 5 x + 5 - 18

Add similar elements:

3 x - 6 x + 5 x = 2 x

7 x + 8 = 2 x + 5 - 18

Add/Subtract the numbers:

5 - 18 = - 13

7 x + 8 = 2 x - 13

Move

8

to the right side

7 x = 2 x - 21

Move

2 x

to the left side

5 x = - 21

Divide both sides by

5

x = - \frac{21}{5}

5 y = 40

\frac{k}{7} = 10

- 3 y + 20 = 2

- 4 + w = - 12

\frac{1}{2} (6 x + 4) = 5 (2 x - 8)
