What is the first step in solving the equation |x - 5| = 1?

• Multiply both sides by 5

• Subtract 5 from both sides

• Add 5 to both sides

• Divide both sides by 5

What should you do after isolating the absolute value sign in an equation?

• Divide both sides by 2

• Multiply both sides by -1

• Add the same number to both sides

• Split the equation into two cases

In the equation |2x + 5| = 31, what are the two resulting equations after splitting?

• 2x + 5 = 31 and 2x + 5 = -31

• 2x + 5 = 31 and 2x + 5 = 0

• 2x + 5 = 31 and 2x + 5 = 1

• 2x + 5 = 31 and 2x + 5 = 5

What is the solution to the equation 2x + 5 = 31?

• x = -13

• x = 13

• x = -18

• x = 18
