Question

If $a+b=10$, then match the corresponding values of $b$
for a given value of $a$.

• A. $b=7$
• B. $b=0$
• C. $b=9$
• D. $b=5$

Answer 1

If $a+b=10$, then $a$ and $b$ can have multiple values in such a way that $a+b$ is always equal to 10.

For example :
if $a=4$, then the corresponding value of $b=6$, because $4+6=10$ and
if $a=6$, then the corresponding value of $b=4$.
