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

To find the values of 'x' and 'y' that satisfy the given equations, we need to solve the system of equations simultaneously.

First, we will solve the equations y = 1.5x + 4 and y = 1.5x - 3.

Since both equations have the same slope of 1.5, they will be parallel and never intersect. Thus, there is no solution that satisfies both equations simultaneously.

Now, let's consider the equation y = 7. Since it does not depend on 'x' and has a constant value of 7, any value of 'x' will give us a corresponding value of 'y' as 7. Therefore, there are infinite solutions for the equation y = 7.

In summary:

• There is no solution that satisfies both equations y = 1.5x + 4 and y = 1.5x - 3 simultaneously.
• The equation y = 7 has infinite solutions, where 'x' can be any real number.
