How do i solve the following geometry problems (systems of equations)?

Question

1. y = x + 3

4x + y = 32

2. 2x = 5y

x + y = 1

3. √12 + √75

4. 4√12(mult.)9√6

5. √12(over)√50 - √27(over)√8

6. (√5 + 2√3) (√5 - 4√12)

7. √48x^7y^8z^3

Answer 1

If math was religion, you would be in the wrong church.  These are not geometry, and we aren't interested in doing all your homework.  But I will do one for you, like #6.  Remember foil?  it still works:

F= sqrt(5)sqrt(5)= 5

O= sqrt(5) times -4 sqrt(12)= -4sqrt(60)

I = 2sqrt(3)tmes sqrt(5)= 2 sqrt(15) and, last but not least,

L= -8 sqrt(36)  

We have to add this mess together, but first, we can do some house-keeping.  sqrt(60)=sqrt(4)sqrt(15) or 2sqrt(15)

and -8 sqrt(36)= -8 * 6 = -48.  

You should be able to sort out the rest.  

Answer 2

why would any1 do that for you

Answer 3

1) x+4= -4x+32

solve for x.

2) 2/5x=1-x
