Answer:
the solution is (-8, 4)
Step-by-step explanation:
Let's use the addition/subtraction method here to eliminate one variable:
-x+y=4
x+3y=4
Combining these two equations results in
4y = 8, so that y = 2. Substituting y = 2 into the second equation, we get:
x + 3(2) = 4, or x = -2.
Then the solution is (-8, 4)
Answer:
2
Step-by-step explanation:
If you want the intersect of M and N, then:
M∩N = {4,7} (common part in M AND N)
Suggestion: tell me that you want answer of all or anyone.
