Question

Anyone know the answer to this ​

Answer 1

Answer:

x = 112

Step-by-step explanation:

The common denominator is 56 because 8*7 is 56

$-\frac{7*7*x}{8*7} -\frac{5*x}{56}+\frac{8*x}{56} = - 92 \\-\frac{49*x}{56} -\frac{5*x}{56}+\frac{8*x}{56} = - 92 \\\frac{-46*x}{56}=-92$

Multiply both sides by 56

-46*x = -92 * 56

-46*x = -5152

Divide by - 46

x = -5152/-46

x = 112

Answer 2

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!
