Atown’s population has increased 35% during the last 8 years and is now 50,100 people. what was the population 8 years ago?

135% of x = 50,100

             x = 50,100 ÷ 1.35 (135% if you're using a calculator)

             x = 37,111

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
