Answer:
We have the equation
we leave the terms with x on the left side of the equation and the independent terms on the right side.
resolving for x we have that
Since we need that the equation doesn't have solution, then it is necessary that the denominator of x be 0 and this occur when
Then, for the equation hasn't solution
Their earnings would be the same after 4 hours
Let the number of hours be x, and the weekly earning be y
So, the given parameters are:
<u>Kimi</u>
So, the equation for Kimi's weekly earning is:
<u />
<u>Jordan</u>
So, the equation for Jordan's weekly earning is:
Equate both equations
Collect like terms
Divide both sides by 2
Hence, their earnings would be the same after 4 hours
