Answer:
it is 61
Step-by-step explanation:
x+29=90
-29
x=61
 
        
                    
             
        
        
        
Your graph will look like an x (ok, the y axis is at a weird place in my plot). The solution (ie., the point where the two graphs intersect) is at (-1,1).
You can also calculate this by equating the two formulas:
x+y = x-y+2 => 2y = 2 => y=1, x =-1.
 
        
        
        
In the event that a line has no y-intercept, that implies it never converges the y-intercept, so it must be parallel to the y-intercept. This implies it is a vertical line, for example, . This slant of this line is vague. In the event that the line has no x-intercept, at that point it never meets the x-intercept, so it must be parallel to the x-pivot. 
If x-intercept is -2 the line would be vertical as the y-intercept = 0.
