first, move all of the variables to one side and add/subtract them
so it looks like this on the left.
Then solve the problem like any other algebra problem.

March 22 Math Class
In classes earlier in march we have been learning type one and type 2 equations in algebra. Today we learned that we would be doing type 3 and type four equations.
All we have to add is one or two steps.
Type two equations are pretty much the same except you have to undo more steps.
Here is an example...
Most people havn't seen the variable in brackets before but don't PANIC it's easy. Since there is multiplication out side of the brackets you have to times everything in the brackets by three. So then the brackets are gone and you now have a type 2 equation. Just make sure to watch the negatives and positives. Oh and don't forget to check your answer!
So now here you see anouther type three equation. As you can see there is a fraction in brackets. Scary i know but just go step by step. First you have to multiply everything in the brackets by four. So them that gets rid of the brackets. Then you just have to work it out normally like a type two equation.

Type II Equations
Today in class we continued our work with type II algebra equations.
Type II equations require two steps to solve.
Below is one example of a type II equation.
As you can see subtraction was used then multiplication.

Type one and type two equations
In class on last Friday, we learned how to solve type two equations. With type two equations, it takes two steps to solve.We had an assignment from the text book with both type one and two equations.
Ex.1) 4a+2=-2
Step 1 4a=-2-2
step 2 4a/4=-4/4
answer a=-1

type one problems/ math class today (March 15)
In math class today, we did'nt really learn much. All we did was work on a homework booklet that was given yesterday. The booklet is basically a practise sheet for type 1 math problems Ex.x + 9 = 17
x = 17 - 9
x = 8
x = 17 - 9
x = 8

Scribe post for March 14th
In class we learned how to do Type I Equations. This is the most basic kind of algebra equation. Here are a few examples.
This is a summary of the work we did in class today. Here are a few heplful links yu can use to help you on these questions.
