9a=6(a+4)

And then I wrote down:

9a=6a+24

but I don't know what to do from there, can someone explain to me please?

The next step is to combine like terms and get the knowns on one side and the unknowns on the other.

Subtract 6a from both sides of the equation.

9a - 6a = 6a - 6a + 24

3a = 24

Divide both sides by 3 to find the value of a.

3a/3 = 24/3

a = 8

**Allyson**, Monday, October 18, 2010 at 2:57pmOkay, when I checked my answer, how come I got 72? when I put 8 As A into the equation.

**Ms. Sue**, Monday, October 18, 2010 at 3:03pmThat's what the original problem states: 72 = 72

9a=6(a+4)

9(8) = 6(8 + 4)

72 = 72

**Allyson**, Monday, October 18, 2010 at 3:03pmSo I could have two answers... ? 8 and 72?

**Ms. Sue**, Monday, October 18, 2010 at 3:07pmNo.

You only need to find what a represents. As we found, in this problem a = 8.

You proved it by substituting 8 for a in the original problem.
