The question in English
Find two numbers whose sum is 45 and whose subtraction is 21
Let
x-------> first number (greater number)
y------> second number
we know that
[tex]x+y=45[/tex] ------> equation A
[tex]x-y=21[/tex] ------> equation B
Adds equation A and equation B
[tex]x+x=45+21[/tex]
[tex]2x=66[/tex]
[tex]x=33[/tex]
Find the value of y
[tex]x+y=45[/tex]
[tex]33+y=45[/tex]
[tex]y=12[/tex]
The two number are [tex]33[/tex] and [tex]12[/tex]
