subtract 4.5 from both sides 

No, there are no solutions.

To solve for 2 veriables, you need 2 equations.

$$\\x - (5 -3x) =7x +4\\\\
x-5+3x=7x+4\\\\
4x-5=7x+4\\\\$$

can you take it from here?

You need to solve 2 equations simultaneously

C+A=512

and

5C+10A=3570

represent the following on number line. 1/2, 2/3, 3/4, 4/5

the lowest common denominator is 60

so you have to make each of these into an equivalent fraction over 60

then you graph them.

You start it then if you need more help ask again.

This unit might help

I do not understand this question.  

This question makes no sense.

A = 1/2bh                  ---Divide both sides by h

A/h = 1/2b                ---Multiply both sides by 2

A/h*2= 1b 

A/h*2 = b

b = A/h*2

If 7x-4y=1 and 5x+3y=52 then x-y=???????

This is a bit of a strange question but here goes.

Well if you add these together you get

7x+5x-4y+3y=1+52

12x -y = 53

11x+x-y=53

x-y=53-11x

No this is a different site that CPhill has given you. 

2x^2 -5 = 7 - 3x

$$\\2x^2 -5 = 7 - 3x\\
\mbox{add 3x and subtract 7 from both sides.}\\
2x^2+3x -5-7 = 0\\
2x^2+3x -12 = 0\\\\
\mbox{Now a=2, b=3, and c=-12}\\$$

now use the quadratic formula to solve it. Here it is

4294967296*(b^16)

or

(2^32)*(b^16)

=15(4)-49-14=60-49-14=-3

-3

5x+(-2x) is the same as 5x-2x which is equal to 3x

This anwser is -1

There is never a last number. Even though the number has a bunch of numbers, but it can always be added by 1. So, someone genius enough made infinity

$$\infty$$ That is the symbol.

no atleast i dont think it does you should follow up but just to say no it does not.

amazing 1+2 = how about you?

An algorithm is a process or sequence of events that leads to some solution.

Ex. Put this in y = mx + b --> 3x - y = 5

The algorithm for this would be:

1) Initial --> 3x - y = 5

2) Place terms with x on the right side

3) Divide both sides by -

4) End --> y = mx + b --> y = 3x - 5

Note: another algorithm would be to add y to both sides and subtract 5 from both sides.

Niiice !!! thank you a lot !!!

Like 5 - 8 + 23? 

c. -6 > -5 is false.

Darn. Your always faster than me Aziz. :)

7 is the same thing as $$\frac{7}{1}$$ so we get:

$$\frac{7}{1}\times\frac{5}{3}$$

Multiply the tops and bottom together.

$$\frac{7\times5}{1\times3}$$

$$\frac{35}{3}$$

or

$$11\frac{2}{3}$$
