Answer:
<h3> The equation has one valid solution and no extraneous of solutions.</h3>
Step-by-step explanation:
Given the expression;
4x/3x+1 = x/2x+10
We are to get the nature of the value of x
Cross multiply;
x(3x+1) = 4x(2x+10)
3x²+x = 8x²+40x
Collect like terms;
3x²-8x² + x - 40x = 0
-5x²+x -40x = 0
-5x²-39x = 0
-5x² = 39x
-5x = 39
x = -39/5
<em>Since we have just one value of x hence, the equation has one valid solution and no extraneous of solutions.</em>
<em></em>
<em></em>
X=
![\frac{-5(+/=) \sqrt{33} }{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-5%28%2B%2F%3D%29%20%5Csqrt%7B33%7D%20%7D%7B2%7D%20)
Or it would be approximately: x≈ 0.37228132, -5.37228132
Hope this helped! ;P
