Solving Linear Equations

What symbol represents "greater than or equal to"?

• >

• ≥

• <

• ≤

• Add 3 to both sides

• Divide by 3 on both sides

• Multiply both sides by 2

• Subtract 7 from both sides

What must you do when dividing both sides of an inequality by a negative number?

• Keep the inequality sign the same

• Add a constant to both sides

• Subtract a constant from both sides

• Flip the inequality sign

• Only 5 satisfies the inequality

• Values less than 5 satisfy the inequality

• All values greater than 5 satisfy the inequality

• No values satisfy the inequality

How is solving an inequality different from solving an equation?

• You only solve for one value

• Equations use inequalities symbols

• Inequalities use addition, not subtraction

• Inequalities give a range of solutions
