5=-9+x-9+x

5 = - 9 + x - 9 + x

x = \frac{23}{2}

Solution steps

5 = - 9 + x - 9 + x

Switch sides

- 9 + x - 9 + x = 5

Group like terms

x + x - 9 - 9 = 5

Add similar elements:

x + x = 2 x

2 x - 9 - 9 = 5

Subtract the numbers:

- 9 - 9 = - 18

2 x - 18 = 5

Move

18

to the right side

2 x = 23

Divide both sides by

2

x = \frac{23}{2}

14 x = 7

\frac{a + x}{b} - \frac{x - b}{a} = 2

6 x - 9 = 75

\frac{3 x - 1}{4} + \frac{x + 3}{6} = 3

- 121 = c + (- 42)
