Today we discussed how to answer a type three equation. The most important thing to know is how to use the distributive property. An example of a type three equation might be something like this:
3(x+8) = -6
The first thing you do is multiply the numbers in the brackets by the 3. Make sure they are done in order:
Ex:
3 times the (x) and then 3 times the (8):
Once that is done you should be left with something like this:
3x+24 = -6
Now you have a type two equation, to solve the rest of the question just complete it like a normal type 2 equation-
3x = -6-24
3x = -30
3x = -30
3 3
X = -10
If you get a question like this:
20 = 4(t/4 – 2)
First, it is often easy to switch the equation around so it looks like this:
4(t/4 – 2) = 20
Now you must add a new step. To figure out the answer do this
4 x t = 1t
1 4
Now finnish the rest of the equation like before.
t-8 = 20
t = 20+8
t = 28
