Solving for x when denominator

WebApr 24, 2024 · In order to find what value (x) makes f (x) undefined, we must set the denominator equal to 0, and then solve for x. f (x)=3/ (x-2); we set the denominator,which is x-2, to 0. (x-2=0, which is x=2). When we set the denominator of g (x) equal to 0, we get x=0. So x cannot be equal to 2 or 0. Please click on the image for a better understanding. WebTo isolate a variable that is in the denominator, you simply cross multiply the equation and collect like terms. Let’s see the examples below: Example 8. 1/(3 x) = 8. Solution. 1/(3 x) = 8. Cross multiply;3x * 8 = 1. 24x = 1. Divide both sides by 24 to get, x = 1/24. Example 9. 3/x =3. Solution. In this case x, is the denominator; Cross ...

WebWhen solving fractional inequalities we should only multiply both sides by positive values otherwise we would change the sign of the inequality. The following videos show how to solve fractional inequalities using the algebraic method, graphical method and analytical method. Solving Fractional Inequalities (1) Using the algebraic method. Example: WebNotice that the numerator and the denominator on the RHS are both square numbers. Also notice that you see 5 on the LHS and 5² on the RHS. So maybe x=2. But (5/2) 2=25/4. The problem is that the numerator and denominator are the wrong way around. So raise both sides to the power of -1. That gives (5/2)-2=4/25, so x=-2.
