b= 3

Explanation:

We will group the numbers with each other and leave the the variable b alone on one side of the equation.

This means that you will have +2 to be next to the 17, but because the 17 is on the other side of the equation, +2 will become -2.

5b = 17 - 2

5b = 15

Therefore,

b = 15/5

now divide both sides of the equation by 5 to get

(cancel(5) * b)/cancel(5) = 15/5

b = 3
