(4x-3)÷(2x+3) + (3+2x)÷(3x^2) =2 so what can x not be

1 answer:

3 0

Remember that if an x=value makes a denominator 0, the entire equation is undefined.

$\frac{4x-3}{2x+3}+\frac{3+2x}{3x^{2}}=2\\\\2x+3=0\\\\2x=-3\\\\x=\frac{-3}{2}\\\\\\3x^{2}=0\\\\x^{2}=0\\\\x=0$

So whenever x = -3/2 or x = 0 the equation is undefined, and that means that x cannot be -3/2 or 0.

Assign two variables for each problem, and write the equations. Do not solve.

Call the number of trumpet players "T" and the number of horn players "H".

We can use the given information to set up equations:

1."<span>the number of trumpet players is 4 times the number of French horn players"
$T=4H$

2. "</span><span>There are 35 trumpet and French horn players in the band."
$T+H=35$

If you were asked to solve you could now do it by substitution:
$4H+H=35$
$5H=35$
$H=7$
$T=4H$
$T=4(7)$
$T=28$ </span>
