Question

the sum of the ages of 4 children born at the interval of two years each is 48 years what is the age of eldest son

write an equation and then solve it​

Answer 1

Answer:

let age of eldest son = x

2nd child = x +2

3rd child = x+4

4th child = x+ 6

sum = x + x+2 + x+4 + x+6 = 48

4x +12 =48

4x = 48 - 12

4x =36

x = 9

eldest son's age = 9 years
