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

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
