    no solutions

    Step-by-step explanation:

    Given the 2 equations

    y = 2x - 1 → (1)

    y = 2x + 6 → (2)

    Substitute y = 2x - 1 into (2)

    2x - 1 = 2x + 6 (subtract 2x from both sides)

    2x - 2x - 1 = 6 (add 1 to both sides)

    0 = 7 ← not possible

    Thus the system has no solution
