Solve the equation 8x - 12=5x+15

Add 12 12 to both sides

8 x = 5 x + 15 + 12 8x=5x+15+12

2 Simplify 5 x + 15 + 12 5x+15+12 to 5 x + 27 5x+27

8 x = 5 x + 27 8x=5x+27

3 Subtract 5 x 5x from both sides

8 x - 5 x = 27 8x-5x=27

4 Simplify 8 x - 5 x 8x-5x to 3 x 3x

3 x = 27 3x=27

5 Divide both sides by 3 3

x = 27 3 x=273

6 Simplify 27 3 273 to 9 9

x = 9 x=9
