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#
