Answer:
B = -24
Step-by-step explanation:
a + b = 23
Since a = 47
47 + b = 23
Subtract 47 from each side
47 - 47 + b = 23 - 47
Therefore:
B = -24
Answer:
b = -24
Step-by-step explanation:
a + b = 23
Substitute 47 for a.
47 + b = 23
Rearrange the equation.
23 - 47 = b
-24 = b
Check your answer by substituting the value you found for b into the equation.
47 + (-24) = 23
