If B+A=10 and A+5=10, then what is B equal to?

 To find the value of \( B \), we first need to solve for \( A \) from the second equation.


Given:

\[ A + 5 = 10 \]


Subtract 5 from both sides:

\[ A = 10 - 5 \]

\[ A = 5 \]


Now that we know \( A = 5 \), we can use the first equation to solve for \( B \).


Given:

\[ B + A = 10 \]


Substitute \( A \) with 5:

\[ B + 5 = 10 \]


Subtract 5 from both sides:

\[ B = 10 - 5 \]

\[ B = 5 \]


Therefore, \( B \) is equal to 5.
