alexandrea and imani each think of a number. alexandras number is 8 more than Imanis number. the sum of two numbers is 50. what is imanis number?



Answer :

apologiabiology
alexandera=a
imani=i

a is 8 more than i or
a=8+i

the sum of the 2 numbers is 50 or
a+i=50

a=8+i
so subsitute 8+i for a in a+i=50
8+i+i=50
8+2i=50
subtract 8 from both sides
2i=42
divide both sides by 2
i=21

subsiutte into a=8+i

a=8+21
a=29



a=29
i=21
