1. subtract 5 from both sides 2. divide 2 from both sides 2x+5 = 27 2x = 22 x = 11

Dude these are so hard how did you do that like it was 9+1

4. anonymous

do you have any idea how to solve this ?

5. anonymous

Solve 2(p+1)=18

6. anonymous

distributive property applies there.

7. anonymous

Nope anytime i learn i forget automatically

8. Owlcoffee

Distributive property: $a(b +c)=ab +ac$

9. anonymous

you have to find the value of x to get make this equation make sense

Listen to @Owlcoffee He is an owl after all which makes him very wise ;)

That would be adding 2 to each side right?

12. anonymous

what do you think the ( ) tells us to do?

13. anonymous

+1 to each side?

Mathematical brackets are symbols such as parentheses that are most often used to create groups or clarify the order that operations are to be done in an algebraic expression. Some bracket symbols, however, have multiple special uses in mathematics.

Owl am I right

First, let's clarify what a term, and a factor is. Whenever you see two numbers or variables separated by a "+" sign, they are called "terms", for example: $$(x+4$$) is a mathematical expression with two terms, there "x" is one term, and "4" is another term, and the "+" sign inbetween them is what separates them. A factor, is exactly the same as a term, but are divided by a product, for example: $a(b+c)$ This is a mathematical expression which presents two factors, "a" is a factor, and $$(b+c)$$ is another factor. At the same time, the second factor $$(b+c)$$ presents two terms inside itself.

$2(p+1)=18$ There are several ways to solve this equation, that would be by dividing both sides of the "=" sign by two: $\frac{ 2(p+1) }{ 2 }=\frac{ 18 }{ 2 }$ Ending up with: $p+1=9$

I have a feeling thats not the end of the equation is it?

22. Owlcoffee

no, an equation is considered solved for when the variable is isolated on any side of the "=" sign, how would you do that?
