Answer:
b=19
Step-by-step explanation:
Given:
b-7=12
Adding 7 to both sides
b-7+7=12+7
b=19
Answer:
b = 19
Step-by-step explanation:
The easiest way to solve equations like this is to do something referred to as "undoing in reverse order." Now, to undo subtraction, you have to add.
b - 7 = 12
b - 7 (+ 7) = 12 (+7)
b = 19
Therefore, the answer is 19.
