Let the present age of a father be x years. Ten years ago, the father was thrice as old as his son. The present age of a son is half the present age of his father. ⇒ 7x – 13x = -12 (Transposing 13x to LHS) Seven times a number is 12 less than thirteen times the same number. Perimeter = 2 (length + breadth) = 2(2x + x) = 2 × 3x = 6xĪs per the condition of the question, we have Let the breadth of the rectangle be x cm. If its perimeter is 60 cm, find the length and the breadth of the rectangle. The length of a rectangle is twice its breadth. Simple Equations Class 7 Extra Questions Short Answer Type If one-third of a number exceeds its one-fourth by 1, find the number. If 5 is added to twice a number, the result is 29. ⇒ 3y – 2y = 6 – 5 (Transposing 6 to RHS and 2y to LHS) ⇒ 3y – 6 = 2y – 2 – 3 (Removing the brackets) Solve the following equations and check the answers. If k + 7 = 10, find the value of 9k – 50. (b) Add 7 to three times a number y gives 1. (b) One-fourth of a number is 2 more than 5.Ĭonvert the following equations in statement form: (a) The sum of four times a number and 5 gives a number five times of it.
