Question 243585
When solving equations, you basically follow the order of operations in reverse. 



{{{3x+15=24}}} Start with the given equation.



{{{3x=24-15}}} Subtract {{{15}}} from both sides.



{{{3x=9}}} Combine like terms on the right side.



{{{x=(9)/(3)}}} Divide both sides by {{{3}}} to isolate {{{x}}}.



{{{x=3}}} Reduce.
