Adding and Subtracting Rational Expressions.
n200080 [17]
A rational expression is a ratio of two polynomials. To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same.

Transform the equation to isolate x: ax = bx 1. How is the value of x related to the difference of a and b?
cestrela7 [59]

Answer:

The value of x is reciprocal of the difference of a and b.

Step-by-step explanation:

We are given the equation, ax=bx+1

On simplifying, we get,

ax=bx+1

i.e. ax-bx=1

i.e. (a-b)x=1

i.e. x=\frac{1}{a-b}

So, we get,

The value of x is \frac{1}{a-b}.

That is, the value of x is reciprocal of the difference of a and b.
