Answer:
no solution
Step-by-step explanation:
If first equation is divided by 2 and the second equation is divided by 3, we get two equations 2x+y=3 and 2x+y= 4. These two lines are parallel and there cannot be any solution to the system
The 4 is the constant term.
The slope-intercept form of a line is the following:
In this form, 
is the shape and 
is the y-intercept. Your line written in this form is
which implies that the slope is 5 and the y-intercept is -2.
