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.
