This is a problem of inequalities. An inequality stands for the relationship between two values when they are different. In this problem, we need to solve for x. So, we have that:

Subtracting 3b from each side of the equation, we have:

Multiplying by
the direction of the inequality changes if
is greater than zero, so we have that solving for x the result is:

Answer:
-2.5?
Step-by-step explanation:
2x+y=25
3x-y=20
solve by adding these two equations together
2x+3x=5x
y-y=0
25+20=45
you get left with
5x=45
divide both sides by 5
x=9
then plug x=9 into one of the 1st equations to solve for y
2(9)+y=25
18+y=25
subtract
y=7
so your numbers are 9 and 7
