We can most easily solve this by simply inserting the known values and solving.
This is saying that x=1 and y=3. Lets replace the variables with them to solve.
Our equation is now 5(1)+3 is less than or equal to to -3.
Solve.
5+3
8 is definitely tly NOT less than -3. It is 11 more than it. The answer is no.
Hope this helps!
