Paul is 5p-7
in 3 years, he will be 5p-4 years
his son is 2p-3 now and 5 years ago was 2p-8
in two years Paul is 5p-5 and his son is 2p-1. That sum is 7p-6
3 apples is 3(2p)=6p. and 4 mangoes is 4(2p-5)=8p-20
That sum is 14p-20 pesos
add the three
4p+1
5p-7
5y-2
3q-5
This is 9p+5y+3q-13
Can add the constants, but can only add like variables
