6m + 5(m - 2) = 56

What is the first step you would do to solve this problem?

• Use the distributive property to remove the parentheses (multiply both terms inside the parentheses by 5)

• Combine like terms

• Subtract 5 from both sides

• Add 2 to both side

When solving equations, you are "isolating" the variable. What does it mean to "isolate" the variable?

• To get the variable alone on one side of the equation?

• To remove the constant from one side of the equation, but leave the coefficient

• To remove the coefficient from one side of the equation, but leave the constant

• To have the variable equal zero
