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"
