12x-3x+4=5x-16

12 x - 3 x + 4 = 5 x - 16

x = - 5

Solution steps

12 x - 3 x + 4 = 5 x - 16

Add similar elements:

12 x - 3 x = 9 x

9 x + 4 = 5 x - 16

Move

4

to the right side

9 x = 5 x - 20

Move

5 x

to the left side

4 x = - 20

Divide both sides by

4

x = - 5

10 x - 10 = 5 (x + 2)

12 = 3 x

4 x - 17 = - 2 x + 25

\frac{x}{2} = 14

\frac{x - 3}{5} = \frac{x + 1}{6}
