Is 2x-5y=32, 2x+3y=0 solvable graphically?
:
Yes, find point of intersection using elimination
2x - 5y = 32
2x + 3y = 0
------------------ Subtraction eliminates x, find y
0 - 8y = 32
y = 32/-8
y = -4
:
find x using the 1st equation
2x - 5(-4) = 32
2x + 20 = 32
2x = 32 - 20
2x = 12
x = 12/2
x = 6
:]
Check solutions in 2nd equation
2(6) + 3(-4) = 0
12 - 12 = 0
:
The lines of the two equations will intersect a x=6, y=-4

Yes if you want




Intersection appears to be (6, -4).

Just to check algebraically,



and you can solve either equation for x using this y value.
