Solving Equations
Hey what’s up you guys Im the blogger for today and I’ll be showing you how to solve multi step equation by simplifying first before solving.

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.

    Hey Michael!

    Thanks for the reminder about the textbook assignment.

    I like how you explained each step as you went through it. Well done!

    How do you think you could have used color and spacing to enhance your work?

    Keep it up!
