3%2F4%2Bx%2F2=12 Start with the given equation.


4%283%2Fcross%284%29%2Bx%2Fcross%282%29%29=4%2812%29 Multiply both sides by the LCD 4 to clear any fractions.


3%2B2x=48 Distribute and multiply.


2x=48-3 Subtract 3 from both sides.


2x=45 Combine like terms on the right side.


x=%2845%29%2F%282%29 Divide both sides by 2 to isolate x.

Answer:

So the answer is x=45%2F2 which in decimal form is x=22.5
