Answer:
x>1 the bottom graph
Step-by-step explanation:
(18x - 9 > 9) and (2x - 4 > -10)
Do the first inequality first
18x - 9 >9
Add 9 to each side
18x - 9+9 > 9+9
18x> 18
Divide each side by 18
18x/18 > 18/18
x >1
Then the second inequality
(2x - 4 > -10)
Add 4 to each side
2x-4+4>-10+4
2x>-6
Divide each side by 2
2x/2 >-6/2
x>-3
Since this is an and
x>1 and x>-3
We take the more restrictive
x>1
X+y=3
x-y=21
x=3-y
3-y-y=21
-2y+3=21
-2y=18
y=-9
x = 3-(-9) = 12
Two numbers are 12 and -9.
Hope this helps.
