15-b=4b-5(5-3)
Multiply the bracket by -5
(-5)(5)=-25
(-5)(-3)=15
15-b=4b-25+15
15-b=4b-10
Move 15 to the other side
Sign changes from +15 to -15
15-15-b=4b-10-15
-b=4b-25
Move 4b to the other side.
-b-4b=4b-4b-25
-b-4b=-25
-5b=-25
divide both sides by -5
-5b/-5=-25/-5

Step-by-step explanation:
In fact, you have undoubtledly encountered non-integer exponents in the past, though you might not have been aware of it at the time! The simplest non-integer power is the square root. Let us review what we do when we take the square root of a number. In taking a square root of 4 for instance, we ask ourselves what number(s) can by multiplied by themselves once in order to give 4? The answer is: well 2 × 2 gives 4 and so does (-2) × (-2). Thus, +2 or -2 raised to the power of 2 gives 4. So the square root of 4 is equal to ±2 (the notation "±" means "plus or minus"). Thus, if Sqrt is to denote the process of taking the square root we have:
22 = 4
Sqrt(22) = Sqrt(4)
2 = Sqrt (4)
