10) Solve using any method
10x+2y=42
5x+y=20
2 answers:
The answer is no solution! Using substitution, you come to 20 = -21, which is a false statement.
Answer:
no solutions
Step-by-step explanation:
10x+2y=42
5x+y=20
Multiply the second equation by -2 to use elimination
-2(5x+y)=20*-2
-10x -2y = -40
Add this to the first equation
10x+2y=42
-10x -2y = -40
--------------------------
0 = 2
This is never true. This means there are no solutions
