4x+5x-2x=9x-12+x

4 x + 5 x - 2 x = 9 x - 12 + x

x = 4

Solution steps

4 x + 5 x - 2 x = 9 x - 12 + x

Add similar elements:

4 x + 5 x - 2 x = 7 x

7 x = 9 x - 12 + x

Group like terms

7 x = 9 x + x - 12

Add similar elements:

9 x + x = 10 x

7 x = 10 x - 12

Move

10 x

to the left side

- 3 x = - 12

Divide both sides by

- 3

x = 4

\frac{- 6 y + ( - 12 )}{- 3} = 2 (12 - 6)

6 = \frac{9}{4} + 2

- 3 (2 t - 1) = t + t + t + 3

- x - 8 = 2 x - 232 x - 23

5 x = 23
