Explanation:
collect terms in a on the left side of the equation and numeric values on the right side.
subtract 2a from both sides.
#4a-2a-5=cancel(2a)cancel(-2a)-3#
#rArr2a-5=-3# add 5 to both sides.
#2acancel(-5)cancel(+5)=-3+5#
#rArr2a=2# To solve for a, divide both sides by 2.
#(cancel(2) a)/cancel(2)=2/2#
#rArra=1" is the solution"#
