6x plus 3y minus 2x plus 5y equals 4x plus 8y.
(-5, 2)
2x +n5y=12
Add the two equations you get 5y = 60 so y = 12 and x = 2
2X + 5Y = 205Y = - 2X + 20Y = (- 2/5)X + 4================now, reading off the function,Y intercept = 4===========
-2x = 20 + 5y-2x - 20 = 5y-2/5x - 4 = yX Intercept = (-10,0) or -10Y Intercept = (0,-4) or -4
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
(-5, 2)
2x +n5y=12
Add the two equations you get 5y = 60 so y = 12 and x = 2
what is the solution of x-5y=10 and 2x-10y=20
2X + 5Y = 205Y = - 2X + 20Y = (- 2/5)X + 4================now, reading off the function,Y intercept = 4===========
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
It equals x+5y simplified
(4, -1)
2x-5y+15=0 -5y=-2x-15 y=(2/5)x+3
-5y +2x = -10 -5y = -2x -10 y = 2/5x +2 So the slope = 2/5 and the y intercept = 2
