2.4x-1.2x=4.8 Start with the given equation.


10%282.4x-1.2x%29=10%284.8%29 Multiply both sides by 10 to clear out the decimals.


24x-12x=48 Distribute and multiply.


12x=48 Combine like terms on the left side.


x=%2848%29%2F%2812%29 Divide both sides by 12 to isolate x.


x=4 Reduce.

Answer:

So the answer is x=4

Check:

2.4x-1.2x=4.8 Start with the given equation.


2.4%284%29-1.2%284%29=4.8 Plug in x=4.


9.6-4.8=4.8 Multiply


4.8=4.8 Subtract. Since the two sides are equal, this verifies our answer.
