Anyone know the answer to this

Kruka [31]

Answer:

x=112

Step-by-step explanation:

First, let's get all of the fractions to a common denominator.

Based on the numbers given (8,56, and 7), let's make all of the denominators be 56

for $\frac{-7}{8} x$ , multiply the numerator and denominator by 7.

$\frac{-7x}{8}$ × $\frac{7}{7}$ = $\frac{-49}{56} x$

we can leave $\frac{-5}{56}x$ as it is

and for $\frac{1}{7} x$ , we cam multiply the numerator and denominator by 8

$\frac{1x}{7}$ × $\frac{8}{8}$ = $\frac{8x}{56}$

Here's the equation now:

$\frac{-49x}{56}$ - $\frac{5x}{56}$ + $\frac{8x}{56}$ =-92

now simlify the fractions

numerators:

-49x-5x+8x=-46x

here's the fraction now:

$\frac{-46x}{56}$ =-92

We can simplify the fraction by 2 so it's $\frac{-23x}{28}$

$\frac{-23x}{28}$ =-92

now multiply both sides by $\frac{28}{-23}$ , which is the reciprocal of $\frac{-23}{28}$ (to isolate the variable)

$\frac{28}{-23}$ × $\frac{-23x}{28}$ =-92× $\frac{28}{-23}$

$\frac{-92*28}{-23}$

x=112

Hope this helps!
