For this case we have the following system of two equations with two unknowns:
We want to know if the point is the solution of the system:
We replace:
, meets the first equation.
does not comply with the second equation.
Therefore, it is not system solution.
Answer:
The point is not system solution
Answer:
Solution (2,1)
Step-by-step explanation:
y = 3x-5
6x+3y=15
Substitute y = 3x - 5 into 6x+3y=15
6x + 3(3x-5
) =15
6x + 9x - 15 = 15
15x = 30
x = 2
Plug in x = 2 into y = 3x-5
y = 3(2) - 5
y = 1
Solution (2,1)
