Answer:
as a decimal: 
as a fraction: 
Step-by-step explanation:
<em>note: i'm going to convert the fractions to decimals because i prefer working with decimals rather than fractions :)</em>
- <em /> <em> </em>as a decimal is<em> </em> <em> </em>as a decimal is<em> </em> <em /> <em />
- <em /> <em> </em>as a decimal is <em> </em>as a decimal is 
- the equation is now  
first, subtract 5.6 from both sides of the equation.
 and and cancel each other out, leaving you with cancel each other out, leaving you with on the right side of the equation. it's not necessary to leave the on the right side of the equation. it's not necessary to leave the in the equation, so just leave it as in the equation, so just leave it as 
- now subtract  from the left side of the equation. from the left side of the equation. , therefore the equation is now , therefore the equation is now 
then divide both sides of the equation by -4.
- you are left with  on the right side of the equation and on the right side of the equation and or or on the left side of the equation, aka on the left side of the equation, aka or or 
and that's it! the solution as a fraction is  and as a decimal is
 and as a decimal is  .
.
if you want to check the solution, just plug one of those values in for  in the original equation. since i converted it all to decimals, i'll check my answer using
 in the original equation. since i converted it all to decimals, i'll check my answer using  for
 for  in
 in  .
.
first, plug in -0.75 for x.
 ⇒ ⇒ 
begin simplifying by multiplying -4 and -0.75.
add 3 and 5.6.
since both sides of the equation are equal, that means your  value is correct and therefore a solution to the equation!! :)
 value is correct and therefore a solution to the equation!! :)
i hope this helped! have a lovely rest of your day <3
