Question

(a)

when two thirds of a number is increased by eight the result is 20

(b)

When the sum of a number and 14 is divided by 3 the result is 4

Answer 1

a) 2x/3 + 8 = 20

2x +24 = 60

2x = 36

x = 18 = the number

(2/3) of 18 = 12, add 8 = 20

b) (x+14)/3 = 4

x+14 = 3(4) = 12

x = 12-14 = -2
