Combine like terms

Subtract 5x from both sides. 

--4=4x+8

Subtract 8 from both sides.

I think the "--4" would be "+4" So, I will go on like that. If I did it wrong please tell me. 

-4=4x

Divide both sides by 4.

-1=x

Yeah. Thank you so much for helping me!! 

How many times does 13 go into 776?

$${\frac{{\mathtt{776}}}{{\mathtt{13}}}} = {\mathtt{59.692\: \!307\: \!692\: \!307\: \!692\: \!3}}$$

59 times. 

So far, we got -59. Now, we need the fraction. 

When you divided 776 by 13, we did not get a number by itself. It came along with a long decimal. This could be converted into a fraction. 

59 times 13 is 767

So, 776-767 is 9 

I think your improper fractions is -59 9/13

You use a^2+b^2=c^2

The c would be the hypotenuse, but remember that this answer would lead you to a squared answer. You have to put a square root to get your answer. 

2x-16x=-55

Combine the like terms:

-14x=-55

Divide -14 from both sides.

$${\frac{{\mathtt{55}}}{{\mathtt{14}}}} = {\mathtt{3.928\: \!571\: \!428\: \!571\: \!428\: \!6}}$$

Uhhh... x=3.928571428714286?

HI!! 

I don't understand how to do any of these 

To find x, we want to isolate it...

Add 14.32 to both sides. 

You get 2.4x=17.52

Divide both sides by 2.4

You get x=7.3

I hope this is correct....

Sorry everybody for all of the questions!!! I missed you all!! I haven't been on here for a while :)

It might just be me, but I do not understand the question. Squared or 2?
