Solve One Step Addition Subtraction Inequalities

-4 + y < -8

• y < 4

• y < -12

• y < -4

What is the first step in solving the following problem? 2x+10=22

• Multiply by 10

• Subtract 10 from each side

• Divide by 2

• Add 10 to each side

Solve.

• x ≤ 12

• x ≥ 14

• x ≥ 12

• x ≥ 23

• Subtract 6 from both sides then divide both sides by 5.

• Add 6 to both sides and multiply both sides by 5.

• Subtract 6 from both sides then multiply both sides by 5.

• Add 6 to both sides and divide both sides by 5.

• Add 10 to both sides of the equation. 

• Add 9 to both sides of the equation. 

• Subtract 3 from both sides of the equation.

• Subtract 9 from both sides of the equation.

For which inequality is x ≥ 4 a solution?

• x + 3 ≥ 1

• x − 3 ≥ 1

• 3x ≥ 1

Solve. (hint: need to get rid of the 3 first)

• x > 19

• x ≥ 11

• x < 11

• x ≤ 19

Which of the following are basic rules used for solving algebraic equations?

• Whatever you do to one side of the equal sign, you must copy and do on the other side of the equal sign.

• Negative signs can be ignored.

• Always do the opposite operation.

• Always start on the left side, regardless of where the variable is.
