How do I make 4 (x+3) = 3 (3x-1) into a simpler form without parentheses. Then substitute 3 for x.

4x+12=9x-3

12+12=27-3

24=24

x=3

Step-by-step explanation:

1) Expand.

4x+12=9x-34x+12=9x-3

2) Subtract 4x4x from both sides.

12=9x-3-4x12=9x-3-4x

3) Simplify 9x-3-4x9x-3-4x to 5x-35x-3.

12=5x-312=5x-3

4) Add 33 to both sides.

12+3=5x12+3=5x

5) Simplify 12+312+3 to 1515.

15=5x15=5x

6) Divide both sides by 55.

/frac{15}{5}=x

7) Simplify / frac{15}{5}

to 33.

3=x3=x

8) Switch sides.

x=3
