) y=1,5x+4, y=1,5x-3,y=7

To solve this system of equations, we can start by setting the two linear equations y = 1.5x + 4 and y = 1.5x - 3 equal to each other:

1.5x + 4 = 1.5x - 3

Since the 1.5x term cancels out on both sides, we are left with:

4 = -3

This is impossible, as it leads to a contradiction. Therefore, there is no solution for this system of equations.
