here is a rational expression,
20+2x/5-x
for what value of x is the rational expression equal to zero?
20+2x/5-x
20/5+2x-x
4+2x-x
4+x
I'm not trying to solve an equation. i am trying to find the value of x in this rational expression.
To find the value of x in the given rational expression where it is equal to zero, we can set the expression equal to zero and solve for x.
In this case, we have the rational expression 20 + 2x / (5 - x).
Setting this equal to zero, we get:
20 + 2x / (5 - x) = 0
To simplify the expression, we can start by isolating the numerator.
Multiply both sides of the equation by (5 - x) to eliminate the denominator:
(5 - x) * (20 + 2x) / (5 - x) = 0 * (5 - x)
This simplifies to:
20 + 2x = 0
Now, we can isolate x by subtracting 20 from both sides of the equation:
2x = -20
Finally, divide both sides by 2:
x = -10
So, the value of x in the rational expression where it is equal to zero is -10.
