0.5(x)+3=9
First you subtract 3 from the problem on the left side. +3 and -3 cancel out. Whatever you do to one side you do to the other so you subtract 3 from the right side to. 9-3=6.
Then bring everything else down.
0.5(x)=6
Since you still want to isolate the (x), you have to divide by 0.5 underneath the multiply by 0.5. This cancels it out. Whatever you do to one side, you do to the other. 6/.5=12
x=12
To check your answer you do the 3 (or more) step check. This check will be 4 steps.
1. Rewrite (rewrite the problem): 0.5(x)+3=9
2. Replace (plug in your answer for x) 0.5(12)+3=9
3. Solve (solve the problem (may take more than one step)): Multiply 0.5 * 12
Bring down: 6+3=9
4. Compare (compare what you got on the left with what if on the right): 9=9
Yes! 9 equals 9! We got it right! The answer is 12.
