Answer:

x = 1, y = 3

Explanation:

The given system of equations is:

y = 4x - 1.......................(i)

y - 2x = 1..................(ii)

Substitute equation (i) into equation (ii)

4x - 1 - 2x = 1

4x - 2x = 1 + 1

2x = 2

x = 2/2

x = 1

Substitute x = 1 into equation (i)

y = 4x - 1

y = 4(1) - 1

y = 4 - 1

y = 3

The solution to the system of equations is x = 1, y = 3
