Together, two people earn $28,000. One earns $2,000 more than the other. How much is the smaller income?
2 answers:
Look at this:
2x+$2,000=$28,000
2x=$28,000-$2,000
2x=$26,000
x=26,000 divided by 2
x=$13,000
P1 +P2= 28 . ----Equation 1
P1+2= P2 . -------Equation 2 . I abbreviate the thousands of $
Using substitution
P1+(P1+2)=28
2P1 +2=28
P1=13
then substitute into equation 2 we get
13+2=p2
P2=15
Therefore one is $15,000
and the other is 13,000
Smaller is 13,000!!!
