5x - 2y = 20
Solve for x:
5x = 2y + 20
x = 2/5y + 4
Solve for y:
-2y = -5x + 20
y = 5/2x - 10
Neither equation can be simplified further without one of the variables already being known.

3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
If as a straight line equation: 5x+2y = 20 then y = -2.5x+10 whereas -2.5 is the slope and 10 is the y intercept
5x 2y = 10
5x-2y=-3 -2y=-5x-3 y=(5/2)x+3/2 slope is 5/2
5x - 2y = 10 2y = 5x - 10 y = 2.5x - 5......which is the equation in slope intercept form.
