One Step Equations and Inequalities Division

Greg wrote in his math journal that 17 - x = 9 is an example of an algebraic equation. Which statement is true about the example Greg wrote in his math journal?

• Greg's example is an equation because there is a variable present.

• Greg's example is an equation because it is a number sentence stating two amounts are equivalent.

• Greg's example is an equation because x can represent any value.

• Greg's example is an equation because there are two numbers present.

The variable, k, is being divided by 11. How should you isolate the variable? ​  

• Divide both sides by 11

• Add 11 to both sides.

• Multiply both sides by 11.

• Subtract 11 to both sides.

Pick the correct inequality.

• A

• B

• C

• D
