The answer is (1.33, 1)

We have a system of two equations:
y = 1.5x - 1
y = 1
________
Using the substitution method, we will substitute y from the second equation in the first equation:
1 = 1.5x -1
________
Now, we just need to solve for x:
1 + 1 = 1.5x
2 = 1.5 x
x = 2 / 1.5 = 1.33

Therefore, the solution is:
x = 1.33
y = 1
Or: (x, y) = (1.33, 1)
