Some equations have multiple steps.
In the first example, we will need to
first combine like terms,
then solve the equation.
|
7x - 9 - 2x = 6
We must first combine 7x and
-2x.
5x - 9 = 6
Now this is a two-step
equation...
5x - 9 + 9 = 6 + 9
5x = 15
x = 3 |

Let's look at another one like this:
|
3y - y - 5 + 8 = 17
We must first combine 3y and
-y then combine -5 and 8.
2y +3 = 17
Now finish...
2y + 3 - 3 = 17 - 3
2y = 14
y = 7 |
