Substitute 6 - 2x for y in the first equation
3x - (6 - 2x) = 4
5x - 6 = 4
5x = 10
x = 2
Plug 5 for x in either equations (I'll use the second equation)
y = 6 - 2 * 2
y = 6 - 4
y = 2
(2,2) is the solution.
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
