If we increased a number by 3 then it becomes equal to 18, find the algebraic expressions.
Write the algebraic expression for:
(i) The area of a reactangle if its length (l) is increased by 5 and breadth (b) is reduced by 3.
(ii) Volume of a cubiod if its length (l) is reduced by 7, height (h) becomes 3 times and width (w) is increased by 2.
