Solving Multistep Inequalities Challenge

What is the first step in solving multi-step inequalities?

• Multiply both sides by a constant

• Add a constant to both sides

• Isolate the variable

• Subtract a constant from both sides

When solving the inequality Y / -6 < 2, what operation is performed after isolating Y?

• Add 6 to both sides

• Multiply both sides by -6

• Subtract 6 from both sides

• Divide both sides by -6

What is the result of distributing 2 in the inequality 2(5X - 1) < 7 + 10X?

• 10X - 1 < 7 + 10X

• 5X - 2 < 7 + 10X

• 10X - 2 < 7 - 10X

• 10X - 2 < 7 + 10X

What does it mean if the variables cancel out and the resulting statement is true?

• No solution

• All real numbers are solutions

• Only negative numbers are solutions

• Only positive numbers are solutions

In the inequality 10X - 2 ≤ 7 + 10X, what happens when you subtract 10X from both sides?

• You get 0 ≤ 7

• You get -2 ≤ 7

• You get 10X ≤ 7

• You get -2 ≤ 0

What is the solution if the variables cancel out and the resulting statement is false?

• All real numbers

• Only positive numbers

• No solution

• Only negative numbers
