# If #1/4x=5-1/2y#, what is the value of x+2y?

First, eliminate the decimals from the given equation to make it simpler.

We get exactly what we want when we rearrange.

Keep in mind that the equation has an infinite number of solutions rather than a single, unique solution because there are two variables.

(This is a straight line's equation.)

To find the value of ( x + 2y ), we need to first solve the equation ( \frac{1}{4}x = 5 - \frac{1}{2}y ) for either ( x ) or ( y ), and then substitute the obtained value(s) into the expression for ( x + 2y ). Let's solve for ( x ):

[ \frac{1}{4}x = 5 - \frac{1}{2}y ] [ x = 4(5 - \frac{1}{2}y) ] [ x = 20 - 2y ]

Now, substitute ( x = 20 - 2y ) into ( x + 2y ):

[ (20 - 2y) + 2y = 20 ]

Therefore, the value of ( x + 2y ) is ( 20 ).

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.
