Answer:
your are very loser but me, is very inteligent but you nono
Step-by-step explanation:
X - y > 2 at (5, 4)
5 - 4 > 2
1 > 2
(5, 4) is not a solution to this inequality
3(x+5)=8x~~~First we distribute (we multiply 3 by x and 3 by 5)
3x+15=8x~~~Remove 3x from both sides
-3x -3x
15=5x~~~~Turn this equation around so x is on the other side
5x=15~~~Divide by 5x
÷5x ÷5x
x=3
