Solving Pre-Algebra linear equations with addition


In solving pre-algebra linear equations with addition, it’s just like normal addition but with a little bit of twist. Linear equations in pre-algebra have letter/s in it, the most common letter we might see in equations is ‘x’.
We will now have an example for solving x with addition to understand how it works, let’s have x – 4 = 6 for the example. In solving this, we need to make sure first that all variables with the same coefficients are on the same side of the equation. For example, -4 and 6 both have no variables, therefore we have to transpose -4 to the right side, leaving us with only x on the left which will make it easier to solve for x. When transposing to the other side, the sign of the variable also changes. If we transpose -4 to the right, then it will be +4 and no longer negative. We will now have x = 6 + 4. For the conclusion of this example, we can say that x = 10.
Another example, 5x – 10 = 15. We must transpose -10 to the other side to make all the variables with the same coefficient the same, remember to change signs when transposing. It will now become 5x = 15 + 10 or in simple term 5x = 25. As you will notice, there is still a value of 5 attached to our x. What you will need to do is to divide both sides with 5 to cancel out the 5 next to the x. After doing so, it will leave us with the answer x = 5.
