How I can find x value in -100 + 130/(1+x) = 0 with steps

[Gali]

Hi

I'm almost starting to get crazy. I'm calculating IRR, and I knew the right answer, but I couldn't solve it form the equation. The right answer 30%. This the x value. But I need to know how to solve it, so I can understand how I can get the x value from such equation.

-100 + 130/(1+x) = 0

Could anyone help, please?:sad:

First - isolate your unknown variable (x) in the equation.

-100 + 130/(1+x) = 0

-100 + 130/(1+x) + 100 = 0 + 100

130/(1+x) = 100

Now continue.......

-100 + 130/(1+x) = 0

Where are you getting stuck? You adding the negative term over to the right-hand side, multiplied through to clear the denominator, multiplied through the parentheses, solved the linear equation, and... then what?

Please be complete. Thank you!

You should know what to add to -100 to get 0. So that is why 130/(1+x) = 100

Now for example, 12/4=3 AND 12/3=4. 10/2=5 AND 10/5=2. In general if a/b=c (and a is not 0), then a/c =b. Use this to solve for (1+x). 1+x is 1 more than x, so how do you find x?
