Answer: Answer is in the steps
Step-by-step explanation:
If the system of equations have the same slope and same y-intercepts then it means that they have infinitely many solutions.
if the system of equations have the same slope but different y-intercepts it means that they have no solution because they will never intersect but will always form parallel lines.
If the system of equations have different slopes and different y-intercepts or have same y-intercepts and different slopes it means that they have exactly on solution.
Answer:
m = 2
n = -4
Step-by-step explanation:
Using elimination method:
4m + n = 4
m - n = 6
--------------------
5m = 10 // n-n = 0, solve for me
m = 10/5 //divide both sides by 5
m = 2
Pick any only of the equation, replace me with it's value.
m - n = 6
2 - n = 6 //subtract 2 on both sides
-n = 6-2
-n = 4 //Change sign, multiply by -1
n = -4
Solution:
m = 2
n = -4
