Answer:
   (x, y) = (5, -2)
Step-by-step explanation:
A graphing calculator provides a quick and easy way to find the solution.
_____
There are several other ways to solve these equations. Or you can estimate where the answer might be using logic like this:
The intercepts of the first equation are ...
- x-intercept = 26/4 = 6 1/2
- y-intercept = -26/3 = -8 2/3
So the graph of it will form a triangle with the axes in the 4th quadrant.
The intercepts of the second equation are ...
- x-intercept = 11/3 = 3 2/3
- y-intercept = 11/2 = 5 1/2
So the graph of it will form a triangle with the axes in the 1st quadrant. The x-intercept of this one is less than the x-intercept of the first equation, so the two lines must cross in the 4th quadrant. 
The only 4th-quadrant answer choice is (5, -2).
 
        
             
        
        
        
Since it says m1 is 120 and it says find m3 don’t you need to multiply or I’m wrong
        
             
        
        
        
Answer:
18 days until they both call him on the same day
Step-by-step explanation:
The common multiples of 6 and 9 is 18, 36, 54, etc. 18 is the first common multiple so Marco's grandparents willl call Marco on the 18th day. please boost me
 
        
             
        
        
        
The rule is to put them in order
        
             
        
        
        
Let the number be x.
Half of that number  =  x / 2
One third of the number  =  x / 3
=  x / 2 + x / 3 = 22.  LCM  =  6.
= (3x + 2 x) / 6  = 22.
5x / 6 = 22.      Cross multiply
5x = 6 * 22.
5x = 132      Divide both sides by 5.
x =  132 / 5
x = 26.4
The number is 26.4.  Cheers.
