4/7. Divide the numerator and denominator by 15.
(x)+(x+2)=3(x+4)-27
2x+2=3x+12-27
2-12+27=17=x
The three integers are 17,19,21
For this case, what we must do is find a point that meets both inequalities.
- <em>y> -2
</em>
- <em>x + y <4
</em>
We have then:
For (0,4):
First inequation:
4> -2 (correct)
Second inequality:
0 + 4 <4 (incorrect)
For (1,4):
First inequation:
4> -2 (correct)
Second inequality:
1 + 4 <4 (incorrect)
For (-3,5):
First inequation:
5> -2 (correct)
Second inequality:
-3 + 5 <4 (correct)
Point (-3,5) is system solution
For (-2,-3):
First inequation:
-3> -2 (incorrect)
Answer:
Point (-3.5) is system solution
