Answer:

not a solution

Explanation:

To determine if (1, 4) is a solution to the system

Substitute x = 1, y = 4 into the equations and check validity

y - 2x = 2

y - 2x = 4 - 2(1) = 4 - 2 = 2 = right side ← True

4x - 6 = 4(1) - 6 = 4 - 6 = - 2 ≠ 4 ← False

First equation is satisfied but second is not

Thus (1, 4) is not a solution of the system
