Take Note: Correctly order the steps below to describe the process (so far) for solving an equation with variables on both sides of the equation.

Combine like terms and use inverse operations to isolate the variable.
Check your solution by substituting it into the original equation.
Work to get the variables together on the same side of the equation and the constants on the other.

Problem 1 Got It? What is the solution of the equation?
Show your work on the canvas. 
You may also complete your work on paper or on a whiteboard and upload or paste a clear picture of it to the canvas.

Problem 1 Got It? Solve the equation from problem 1 by first subtracting 5x from each side instead of 2x. Show your work on the canvas. Do you get the same solution?

No, subtracting 5x yields a different solution.

Yes, 4 is the solution either way.

Take Note: Place the five steps for solving equations in chronological order.

Combine like terms on each side of the equation.
Use the properties of equality to get the variable terms on one side of the equation and the constants on the other.
Use the properties of equality to solve for the variable.
Check your solution in the original equation.
Use the Distributive Property to remove any grouping symbols. Use properties of equality to clear decimals and fractions.
