5y + 5y = 10y
15y+14=2(5y+6) 15y+14=10y+12 15y+14-14=10y+12-14 15y=10y-2 15y-10y=10y-2-10y 5y=-2 y=-2/5
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
(-5, 2)
2x +n5y=12
what is the solution of x-5y=10 and 2x-10y=20
x = 2, y = 1
-2x = 20 + 5y-2x - 20 = 5y-2/5x - 4 = yX Intercept = (-10,0) or -10Y Intercept = (0,-4) or -4
5y + 5y = 10y
x = 2 and y = 1 The lines intersect at the point (2, 1)
15y+14=2(5y+6) 15y+14=10y+12 15y+14-14=10y+12-14 15y=10y-2 15y-10y=10y-2-10y 5y=-2 y=-2/5
solv by cramr's rule [ 2x - 5y ] = 2 , [-4x + 10y ] = 1
2(x - 5y)
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
(-5, 2)
2x +n5y=12
It is: 7x+10y
