Modeling With Two-Step Equations

I can write two-step algebraic equations based on modeling tiles

• 4x+2=10

• 6x=10

• 2x+4=10

• 6x=10x

• -24

• -9

• -6

• 6

• -3

• 7

• -1

• 5

I can write two-step equations to model real-world situations and then solve the equations. An ice cream shop is expected to sell 300 cones in a day. They have already sold 75 cones today and expect to sell 50 cones an hour for the remainder of the day. How many hours will the shop need to meet their goal? Write an equation

• 300+50=75x

• 50x+75=300

• 75x+50=300

• 75x+50x=300x
