4x-0.92+=+3%28x-0.04%29 Start with the given equation

4x-0.92+=+3x-0.12 Distribute

100%284x-0.92%29=100%283x-0.12%29 Multiply both sides by 100 to move the decimal on each number 2 times. This will make every number a whole number.

400x-92=300x-12 Distribute and multiply



400x=300x-12%2B92Add 92 to both sides


400x-300x=-12%2B92 Subtract 300x from both sides


100x=-12%2B92 Combine like terms on the left side


100x=80 Combine like terms on the right side


x=%2880%29%2F%28100%29 Divide both sides by 100 to isolate x



x=4%2F5 Reduce

--------------------------------------------------------------
Answer:
So our answer is x=4%2F5 (which is approximately x=0.8 in decimal form)
