Answer:
y determinant is 3
x determinant is 2
system determinant is 1
Answer:
x=3
y = 2
Solution is (3,2)
Step-by-step explanation:
x + 2y = 7
x - 2y = -1
Solve the system of equations by elimination method
LEts add both equations
x + 2y = 7
x - 2y = -1
------------------
2x +0 = 6
2x = 6
Divide both sides by 2
x= 3
Now plug in x=3 in first equation
x + 2y = 7
3 + 2y = 7
subtract 3 from both sides
2y = 4
divide both sides by 24
y = 2
Solution is (3,2)
