What does it mean to isolate a variable in an equation?

• To add it to both sides of the equation

• To combine it with other variables

• To get it alone on one side of the equation

• To multiply it by a constant

If you have the equation 4X = 16, what operation would you use to isolate X?

• Multiply both sides by 4

• Subtract 4 from both sides

• Divide both sides by 4

• Add 4 to both sides

In the equation X + 5 = 25, what is the first step to isolate X?

• Subtract 5 from both sides

• Divide both sides by 5

• Multiply both sides by 5

• Add 5 to both sides

What is the purpose of using inverse operations in solving equations?

• To add more variables to the equation

• To undo operations and isolate the variable

• To eliminate the variable

• To make the equation more complex

When dealing with complex equations, what is the recommended approach?

• Solve it without combining like terms

• Ignore the distributive property

• Reduce it to a two-step equation

• Add more variables to the equation
