Solve the rational equation x divided by 6 equals x squared divided by quantity x minus 1 end quantity, and check for extraneous
pychu [463]

Answer:

x = 0 and x = \textrm{negative one fifth}

Step-by-step explanation:

Given:

The rational equation to solve is given as:

\frac{x}{6}=\frac{x^2}{x-1}


We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,

x\times (x-1)=6\times x^2\\x^2-x=6x^2\\\textrm{Bringing all variables to the right side, we get:}\\6x^2-x^2+x=0\\5x^2+x=0\\x(5x+1)=0\\x=0\ or\ 5x+1=0\\x=0\ or\ x=-\frac{1}{5}


Now, for x=0, the rational equation is equal to 0. So, x=0 is a solution.

Also, x=-\frac{1}{5} is also a solution as the equation's denominator is defined at that point.

So, no extraneous solution.

6(r+3)-4=2r+10+4r how do you slove that
Vinvika [58]
Simplify 2r + 10 + 4r to 6r + 10

Expand it

Simplify 6r + 18 - 4 to 6r + 14

Cancel 6r on both sides

Since 14 = 10 is false, there is NO solution for this equation so no answer.
