Explanation:
Multiply each term by
cancel(x+3)*5/cancel(x+3)-2(x+3)=cancel(x+3)*7/cancel(x+3)
5-2(x+3)=7
Solve the term that has parenthesis using the distributive property
5-2x-6=7
Group like terms
5-6-2x=7
-1-2x=7
When you take a number or a variable to the other side of an equation, the sign changes.
-2x=7+1
-2x=8
Divide both sides by
(cancel(-2)x)/cancel(-2)=8/-2
x=-4
