Solving One Step Equations and Models

When solving an equation, our goal is to:

• add all the numbers together.

• use a calculator.

• eat lunch.

• isolate the variable to solve.

What is the equation for this hanger diagram?

• 5m = 50

• 5m -50 = 5

• m + 5 = 50

• m = 50 - 5

Solve for x.

x + 12 = 20

• x = 8

• x = -32

• x = 32

• x = -8

Solve for y:

y - 7 = 10

• 17

• -3

• 3

• -17

Which equation matches the hanger model?

• y - 7 = 21

• y + 7 = 21

Solve for y.

• y=6

• y =2

• y=3

• y= 9

Solve for x.

• x=6

• x=3

• x=1

• x=2

Which equation represents the hanger pictured?

• 4= 2x + 4

• 12= 4 2x

• 16 = 4 + 2x

• 4444= 4 + 2x

• 14= 4 * 2x

Which equation represents the hanger pictured?

• 2x + 3 = 9

• 2x + 3 = 15

• 2x + 3= 33333

• 2x - 3 = 15

• 3 * 2x = 33

What is the equation for this hanger diagram?

• 2 (y+10) = 31

• 31 = 2y - 10

• 10 + 2y =41

• 2y + 10 = 31
