Thread: solving algebraic equations

any of u a math genius or close to it i need help on this problems if i dont do this i wont get to walk on graduation sad right help me

math challenged here >.>

solving rational equations solve using any method check for solutions

1) 7/x +1/2 = 4

2) x/4 + 1/2 = 5

3)4/x + 1/3 = 10

4)1/2x + x/3 = 7

5) -2/x+3 =1/x+1

6) 4/x+2 = -3/x-3

7) -4/x+1 = 2/x-1

8) 3/x+4 = 9/x-2a

First of all your link is not a hyperlink...its just blue text

and secondlyu

I will do five for you

$\displaystyle \frac{-2}{x+3}=\frac{1}{x+1}$

Cross-multiplying you get

$\displaystyle -2(x+1)=x+3$

Expanding you get

$\displaystyle -2x-2=x+3\Rightarrow{3x=-5}\Rightarrow{x=\frac{-5}{3}}$
