Domain is all the possible inputs of an equation. In this example, the only concern is the x + 5 because the denominator cannot equal 0 because we can't divided by 0. So we set x + 5 equal to zero and solve for x.
x + 5 = 0
x = -5
The restriction is that x cannot equal -5.
Let's solve this problem step by step.
28=8b+13b-35
Step 1: Bring 35 to 28.
28=8b+13b-35
+35 +35
63=8b+13b
Step 2: Add 8b and 13b.
63=21b
Step 3: Divide both sides by 21.
63/21=21b/21
So, the answer for this problem is 3=b.
