Solving two step equations

When solving two step equations,they will have the following form:

ax + b = c or ax − b = c

When solving equations of the form ax + b = c, you can subtract b from both sides of the equation and then divide both sides by a.

When solving equations of the form ax − b = c, you can add b to both sides of the equation and then divide both sides by a.

Note that there is nothing special about subtracting b or adding b to both sides and then then divide by a!

You can instead start by dividing both sides by a and then subtract or add something to both sides. You will end up with the same answer.

In practice, mathematicians prefer to add or subtract something from both sides and then divide by a because calculations are usually easier.

Example #1:

Example #2: You can solve the problem above by dividing both sides by a first before adding or subtracting something from both sides.
