When multiplying both sides by 4, I will tell students that they may want to write 4 as 4/1 and place any other integer values over 1. Using example 3, they would have 4/1 and -32/1. I think this at least helps students see the "canceling" affect on the variable side of the equation.
To combine them is pretty easy, you just add them together and make sure that they are all on the same side of the equation. First, we will combine all like terms on each side of the equation: Since the 15 and 10 are both constants we combine them to get 25. The 4x and -3x each have the same variable (x), so we can add them to get 1x.

Solving Equations with Variables on Both Sides of the Equation Remember, when solving equations our goal is the get the variable by itself. Therefore, the variable cannot be on both sides of the equation. We must get the variable on one side of the equal sign and the constant term(s) on the other.
Linear equations in one variable are equations where the variable has an exponent of 1, which is typically not shown (it is understood). An example would be something like \(12x = x – 5\). To solve linear equations, there is one main goal: isolate the variable. In this lesson, we will look at how this is done through several examples.
