At first, it is important to identify that this is a linear equation, usually in the form of y = mx + b. These equations are used for straight line graphs. The most important rule to remember when solving th...

4x + 10 = 18 4x= 18-10 4x= 8 x=8/4 x=2

We’ve got to remember that expand means to multiply out, so that word is really important because it tells us what operation to use. The order we multiply in can be remembered using the word FOILS, which sta...
