Solving Equations with Variables on Both Sides

What is the first step to take when solving equations with variables on both sides?

• Use inverse operations

• Check if the equation is balanced

• Distribute any constants

• Combine like terms on both sides

In the equation 8X - 7 = 4X + 21, why do we subtract 4X from both sides?

• To balance the equation

• To eliminate the constant term

• To isolate the variable on one side

• To make the equation simpler

What is the solution to the equation 4X = 28?

• X = 14

• X = 7

• X = 4

• X = 28
