Question
Solve the equation
Solve for a
Solve for b
Solve for r
a=r+b
Evaluate
b−a=nq−r×1−nq−r×0
Simplify

Evaluate
nq−r×1−nq−r×0
Any expression multiplied by 0 equals 0
nq−r×1−nq−0
Any expression multiplied by 1 remains the same
nq−r−nq−0
Removing 0 doesn't change the value,so remove it from the expression
nq−r−nq
The sum of two opposites equals 0
