Y = 7(15 + x)   Use the Distributive Property
         Y = 105 + x     Subtract 105 from both sides
Y - 105 = x               Switch the sides to make it easier to read
          x = Y - 105

\(y=7(15+x)\)  \(\text{Given equation}\) 

\(\dfrac{y}{7}= 15+x\)  \(\text{Divide each sides by 7}\) 

\(\dfrac{y}{7}-15=x\)  \(\text{Subtract 15 from both sides}\) 

\(x=\dfrac{y}{7}-15\)  \(\text{Solution}\)
