Question 1062305: Estimate the solution of the linear system graphically. Then check the solution algebraically ( 3 different problems.)
y= -6
x= 6
---------------------------------------------
2x - 3y =9
x= -3

5x + 4y = 16
y= -16 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! The first is (6,-6). That is where the vertical x line at x=6 intersects the horizontal y line a y=-6.
---------
2x - 3y =9
x= -3
The first is -6-3y=9
-3y=15
y=-5 solution (-3,-5) This intersects a vertical line where x=-3
--------
5x + 4y = 16
y= -16
5x-64=16 by substitution.
5x=80, x=16 solution (16,-16)
