Which choice is the solution to the system? x + 2y = 1 y = - 1 2 x + 4

no solutions

Step-by-step explanation:

x + 2y = 1

y = - 1 / 2 x + 4

Substitute the second equation into the first

x + 2 (-1/2x+4) = 1

Distribute

x - x + 8 = 1

Combine like terms

8=1

This is never true so there are no solutions
