Question 1

Q1) Express each of the following statements in algebraic form :

(i) The sum of 8 and x is equal to y.

(ii) x decreased by 5 is equal to y.

(iii) The sum of 2 and x is greater than y.

(iv) The sum of x and y is less than 24.

(v) 15 multiplied by m gives 3n.

(vi) Product of 8 and y is equal to 3x.

(vii) 30 divided by b is equal to p.

(viii) z decreased by 3x is equal to y.

(ix) 12 times of x is equal to 5z.

(x) 12 times of x is greater than 5z.

(xi) 12 times of x is less than 5z.

(xii) 3z subtracted from 45 is equal to y.

(xiii) 8x divided by y is equal to 2z.

(xiv) 7y subtracted from 5x gives 8z.

(xv) 7y decreased by 5x gives 8z.

Solution 1:

(i) 8 + x = y

(ii) x - 5 = y

(iii) 2 + x > y

(iv) x + y < 24

(v) 15 x m = 3n

(vi) 8 x y = 3x

(vii) 30 b = p

(viii) z - 3x = y

(ix) 12 x x = 5 z

(x) 12 x x > 5z

(xi) 12 x x < 5z

(xii) 45 - 3z = y

(xiii) 8x y = 2z

(xiv) 5x - 7y = 8z

(xv) 7y - 5x = 8z
