Question
solve each equation and check the result
7 3 40
x-5 - x+5 = x^2 - 25
there is a line in between each equation
how would i start something like this?

Surely there is an explanation, it makes no sense to me.

its solving rational equations
7 3 40
- - - = -
x-5 x+5 x^2-25
7 3 40
- - - = -
x-5 x+5 x^2-25

sorry i don't know how else to put the equation on the forum

Is this
7/(x-5) - 3/(x+5) = 40/(x^2-25) ?
If so get a common denominator (x^2-25) so it becomes
7(x+5)-3(x-5)=40
and one can solve that. Otherwise, I can make no sense from your problem.
