Step-by-step explanation:

The equation is given below as


0.25x+0.05\left(66-x\right)=6.70

Step 1:

Open up the parenthesis using the distributive property of multiplication


\begin{gathered} 0.25x+0.05(66-x)=6.70 \\ 0.25x+3.3-0.05x=6.70 \end{gathered}

Step 2:

Collect similar terms, we will have


\begin{gathered} 0.25x+3.3-0.05x=6.70 \\ 0.25x-0.05x=6.70-3.3 \\ 0.20x=3.4 \\ divide\text{ both sides by 0.20} \\ (0.20x)/(0.20)=(3.4)/(0.2) \\ x=17 \end{gathered}

Hence,

The final ansswer is


x=17
