Answer:
<h3>
b=
</h3>
Step-by-step explanation:
4b+5=t
First, you must get the variable alone! Substract 5 from both sides!
4b<u>+5=t </u>
-5 -5
The 5 cancels out because 5-5=0
The new equation is 4b=t-5
You must divide by 4 to get the variable alone since your solving for b!
<u>4b=t-5</u>
4 4
b= 
This is your answer!
