You can put this solution on YOUR website! Hi,
I'll help you with the first one and let's see if you can do the others. Deal?
x/3=4/x+1
Multiply both sides by 3(x+1) to get:
x(x+1)=3(4)
Rewritten as:
x^2+x=12
Subtract 12 from both sides to get:
x^2+x-12=0
Now factor toget:
(x+4)(x-3)=0
Solve for x results in:
x=-4
x=3
We can plug these answers into the original problem to see if they are correct.
Make sense?
