Answer:
Solving the inequality
, we get 
Step-by-step explanation:
We need to solve the inequality 
Using the BODMAS rule, first we will solve the bracket:

Now, we will subtract 28 from both sides

Subtracting -7k on both sides

Finally, divide both sides by -8 and inverse the inequality, as we are dividing with a minus digit.

So, solving the inequality
we get 
273 737 782 + 937 382 928 = 1 211 120 710
Standard form is
ax+by=c
get all x and y on one side
first distribute
-1(x-y)=-x+y
now weh have
8-x+y=-3x+5
add 3x to both sides
8+2x+y=5
minus 8 from both sides
2x+y=-3
