How do you cross multiply #\frac{4x}{x+2}=\frac{5}{9}#?

Answer 1

In cross-multiplication, we multiply the numerator of each (or one) side by the denominator of the other side. This could be represented as:

So, in this case,

#(4x)/(x+2)=5/9#

By cross multiplication,

#9*(4x)=5*(x+2)#

#36x=5x + 5*(2)#

#36x-5x=10#

#31x=5#

#x=5/31#

To cross multiply the equation \frac{4x}{x+2}=\frac{5}{9}, you would multiply the numerator of the first fraction (4x) by the denominator of the second fraction (9), and multiply the denominator of the first fraction (x+2) by the numerator of the second fraction (5). This can be written as:

4x * 9 = (x+2) * 5.

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.
