Question

Evaluate :

(i) (23 – 15) + 4

(ii) 5x + (3x + 7x)

(iii) 6m – (4m – m)

(iv) (9a – 3a) + 4a

(v) 35b – (16b + 9b)

(vi) (3y + 8y) – 5y

Answer 1

(i) (23 – 15) + 4 = 8 + 4 = 12

(ii) 5x + (3x + 7x) = 5x + 10x = 15x

(iii) 6m – (4m – m) = 6m – 3m = 3m

(iv) (9a – 3a) + 4a = 6a + 4a = 10a

(v) 35b – (16b + 9b)= 35b – 25b = 10b

(vi) (3y + 8y) – 5y = 11y – 5y = 6y
