What are the solutions to the equation x - 7/x = 6

bearhunter [10]

The answer is C that is X=7 and X=-1

multiple x through the given equation to get rid of a fraction. It will be

${x}^{2} - 7 = 6x$

After that bring 6X to the LHS of the equation

so that it will look like the general equation that is

${x}^{2} - 6x - 7 = 0$

Use the quadratic formula (or any other approach to find the values of x

You will arrive at

$x = 7. - 1$

-2/3- (-3/4) Simplify if needed Brainliest Also, 5/6+5/12

Answer:

$-\frac{2}{3} - (-\frac{3}{4}) = \frac{1}{12}$

$\frac{5}{6} + \frac{5}{12} = \frac{5}{3}$

Step-by-step explanation:

Given

$-\frac{2}{3} - (-\frac{3}{4})$

Required

Solve:

$-\frac{2}{3} - (-\frac{3}{4})$

Open bracket

$-\frac{2}{3} - (-\frac{3}{4}) = -\frac{2}{3} +\frac{3}{4}$

Take LCM

$-\frac{2}{3} - (-\frac{3}{4}) = \frac{-8+9}{12}$

$-\frac{2}{3} - (-\frac{3}{4}) = \frac{1}{12}$

$\frac{5}{6} + \frac{5}{12}$

Take LCM

$\frac{5}{6} + \frac{5}{12} = \frac{10+5}{12}$

$\frac{5}{6} + \frac{5}{12} = \frac{15}{12}$

Divide by 3/3

$\frac{5}{6} + \frac{5}{12} = \frac{5}{3}$
