Modeling and Solving One Step Equations

Write the equation of this model

• 4 = 9

• 2x + 2 = x + 8

• 2 + 2 = 1 + 8

• 2x + 1 = x + 1

• F

• G

• H

• J

• F

• G

The goal of solving a one, two, or multi-step equations is to:

• Find the constant

• Find the coefficient

• Find the value of the variable

I can write one-step equations to model real-world situations and then solve the equations. Write an equation: A chicken lays about 250 eggs a year. If a chicken has already laid 65 eggs, how many more is she expected to lay this year?

• x+65=250

• 250+65=x

• 65x=250

• 65x+250=315

I can write one-step equations to model real-world situations and

then solve the equations.

Solve the equation:
