One Step Equations with Adding and Subtracting

A scuba diver dove down 25 feet, then swam up 11 feet. Which equation represents this and the diver's current position?

• -25 + - 11 = -36

• -25 + 11 = -14

• -25 + 11 = -36

• -25 + 11 = 14

Which expression has the sum of 0?

• 0 - 8

• 0 + -8

• -8 - 8

• 8 + (-8)

For 2-(-2).... the two negatives turn this equation into...

• 2-2

• 2+2

• 2+-2

Which expression is represented by this model?

• -7 + 7

• -7 + 10

• -7 + 3

• -7 + 0

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

x - 8 = -5 

• 13

• -13

• 3

• -3

7 + ^a⁄₃ = 5

• a= -2

• a= -6

• a= 3

• a= 15

The objective when solving an equation is to....

• isolate the variable.

• check the solution.

• guess and check.

• Combine Like Terms.

What is the inverse operation of adding?

• Adding

• Subtracting

• Multiplying

• Dividing
