2x+3y=13 3x-y=3 x=2
y = (13 - 3x)/2 and that cannot be simplified further.
(2, 7)
3x -5y = 13 -5y = -3x+13 y = 0.6x -2.6 in slope intercept form So the y intercept is -2.6
Solved for y: y=(3x-13)/5 Solved for x: x=(5y+13)/3
x equals -3, and y equals 1.
4x - y = 1 3x + y = 13 Add the equations: 7x = 14 so that x = 2 and then, by the first equations, 4*2 - y= 1 so that y = 7
(3, -4)
y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7
x = 3, y = -4
x = 3 and y = -4
