Question

The system shown has _____ solution(s). y = 1/2 x 1 2y - x = 6 no one infinite

Answer 1

The system y = 1/2 x 1 2y - x = only has ONE solution (4,5).

Explanation:

Answer 2

y = x + 1, the first equation
2y - x = 6, the second equation
Replace y in the second equation with the first one we get:
2(x + 1) - x = 6
solve the equation we get x = 4
so, y = 4 + 1 = 5
The system y = x +1, 2y - x = 6 has one solution (4, 5)
