Question

Solve the system of equations by substitution. What is the solution for x? 2x + y = 1 4x + 2y = −1

Answer 1

{2*x + y = 1, 4*x + 2*y = -1}
Divide each side of the second equation by 2.
{2*x + y = 1, 2*x + y = -1/2}
1 does not equal -1/2
There is no solution.

Answer 2

2x + y = 1
2x + y = -1/2

False
