Question: 4b - 5 = -t

step 1: add 5 to both sides

now it's: 4b = 5 - t

step 2: divide both sides by 4

answer: b = ( 5 - t ) / 4

notes: The trick with this kind of problem is to isolate the variable that you are trying to solve for, in this case "b." Adding 5 to both sides isolates "b" and dividing by 4 gives the final answer.
