Question

the sum of abi and bens ages is 18 the diffference in their age is 4 years abi is older
write an equation for the sum of their ages

write an equation for the difference in their ages

Answer 1

X = bens age
X + 4 = abi
Total = 18
2x + 4 = 18
Subtract 4 from both sides
2x = 14
Divide both sides by two
X = 7

Answer 2

Abi is 11
Ben is 7
So let’s say that n=11 and p=7
n+p=18 ???
