Solve forxin terms ofaandb

2a + 3(x-2) = ax + b

3

^^( that's 2a over 3)

I know it's probably simple but I can't get it!

Thank Masters!

So I can't get*x*as a 'whole' number? That's what I was having trouble with.

You're dealing with 'literals' here. This means your answer will not be a number. Both a and b are unknown variables at this time, so we just solve for whichever variable is required. It's like converting formulas like this:

Distance = rate X time

Rate = distance divided by time

Time = distance divided by rate.
