0.2%28x%2B0.2%29%2B0.5%28x-4%29=5.74 Start with the given equation


20%28x%2B0.2%29%2B50%28x-4%29=574 Multiply both sides by 100 to move the decimal 2 places over.

20x%2B4%2B50x-200=574 Distribute


70x-196=574 Combine like terms on the left side


70x=574%2B196Add 196 to both sides


70x=770 Combine like terms on the right side


x=%28770%29%2F%2870%29 Divide both sides by 70 to isolate x



x=11 Divide

Answer:
So our answer is x=11
