Step-by-step explanation:

sorry if i got it wrong

To determine whether a solution a set of a system of linear inequalities is right, you simply plug back into the equation to check your work. If the solution equals and is mathematically correct, then that's the answer. For Example, use the equation,

5x = 10

Let's say you got an answer of x = 4. Plug it back into the equation 
5(4) ≠ 10. As you can see the answer is wrong. This shows you that the answer is wrong. 

The correct answer is x = 2
