<PRE><B>Question 163754</B>


{{{3/4+x/2=12}}} Start with the given equation.



{{{4(3/cross(4)+x/cross(2))=4(12)}}} Multiply both sides by the LCD {{{4}}} to clear any fractions.



{{{3+2x=48}}} Distribute and multiply.



{{{2x=48-3}}} Subtract {{{3}}} from both sides.



{{{2x=45}}} Combine like terms on the right side.



{{{x=(45)/(2)}}} Divide both sides by {{{2}}} to isolate {{{x}}}.
