Okay so in our class today Ms Nicholson taught us how to solve equations that need to be simplified first to get the answer. Here’s an example:
EX: 2(x + 1) = 4
Okay so to solve this we have to simplify both sides first so:
2(x + 1) = 4
= 2x + 2 = 4 now it’s already simplified now we can start finding the value
of x , to do that we have to get the x all by itself so:
= 2x + 2 - 2 = 4 – 2 and since this is an EQUATION, the RULE is: what ever you do on
The other side you do to the other side so that it will remain balanced.
= 2x = 2 Now that the x is all by itself we have to divide both sides by the number
coefficient of x:
= 2x/2 = 4- 2
after we divided both sides, we are left with the answer:
x = 2
we can now check if it’s correct:
2(x + 1) = 4
= 2x + 2 = 4
= 2x + 2 – 2 = 4 – 2
= 2(2) = 4
= 4 = 4 and that’s it were done 4 equals 4 right? So that means that the value of x that we have is correct.
That all for my scribe hope you understand it. And oh yeah REMINDER to my
classmates we have an textbook assignment. Its page 91 27-40(odd) and page 98
1-12(odd) 32, 34. and that ends my scribe.
