    y = 4x + 5 and y = 4x - 5 has no solutions

    y = 4x + 5 and y = One-fourthx + 5 has no solutions

    Step-by-step explanation:

    For y = 4x + 5 and y = 4x - 5 slnce y = y then 4x + 5 must be = 4x - 5 if we add like terms

    4x - 4x = - 5 - 5 ➡0 = - 10 doesn't make sense so first equation has no solution.

    Do tge same with y = 4x + 5 and 2y = 8x + 10 since 2y is twice of y then 8x + 10 must be twice 4x + 5

    If we simply multiply 4x + 5 by 2 we can clearly see that it is equal to 8x + 10 therefore the second equation has solution

    Now for y = 4x + 5 and y = One-fourthx + 5

    One-fourth of x = 1/4

    again since y=y 4x + 5 must be = 1/4x + 5 but that doesn't seem possible.

    The answer would be first and third option y = 4x + 5 and y = 4x - 5 and y = 4x + 5 and y = One-fourthx + 5 has no solutions
