3y+5(x+3)+2=2y+7

To solve x:

1- Remove parentheses by using distributive property:


3y+5x+15+2=2y+7

2-Combine like terms;


3y+5x+17=2y+7

3-Leave x in one side of the equal sing:

- Subtract 3y in both sides of the equation


\begin{gathered} 3y-3y+5x+17=2y-3y+7 \\ 5x+17=-y+7 \end{gathered}

-Subtract 17 in both sides of the equation:


\begin{gathered} 5x+17-17=-y+7-17 \\ 5x=-y-10 \end{gathered}

-Divide both sides of the equation into 5:


\begin{gathered} (5)/(5)x=-(y)/(5)-(10)/(5) \\ \\ x=-(y)/(5)-2 \end{gathered}Then, the solution for x in the given equation is:
x=-(y)/(5)-2
