         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
[tex]y=7(15+x)[/tex]  [tex]\text{Given equation}[/tex] 

[tex] \dfrac{y}{7}= 15+x [/tex]  [tex]\text{Divide each sides by 7}[/tex] 

[tex]\dfrac{y}{7}-15=x[/tex]  [tex]\text{Subtract 15 from both sides}[/tex] 

[tex]x=\dfrac{y}{7}-15[/tex]  [tex]\text{Solution}[/tex]
