How do you solve #2/(3+x) = 25#?

Answer 1

Ethan Adkins

First multiply both sides by #(3+x)#:

#2=25(3+x)=75+25x#

Then collect like terms:

#25x=-73#

Divide both sides by #25#:

#x=-73/25=-2.92#

To solve the equation 2/(3+x) = 25, we can start by cross-multiplying. This gives us 2 = 25(3+x). Next, we distribute 25 to both terms inside the parentheses, resulting in 2 = 75 + 25x. We then subtract 75 from both sides to isolate the term with x, giving us -73 = 25x. Finally, we divide both sides by 25 to solve for x, which gives us x = -73/25.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
