10y + 8y = 18y = 15 y = 15/18 y = 5/6 = 0.833333.....
10y = 2y - 6y + 7 10y =-4y + 7 10y +4y = 7 14y = 7 y = 1/2 = .5
X=7 y=5
6y-5=8+10y 6y-10y=8+5 -4y=13 y=-3.,25 because: 6*3.25-5=-24,5 and 8+10*3.25=-24,5 true
y=3.25 I believe that is the answer.......I have not math like that in a while.
10y + 8y = 18y = 15 y = 15/18 y = 5/6 = 0.833333.....
10y= 6y+5+3y 10y=6+9y y=6
10y = 2y - 6y + 7 10y =-4y + 7 10y +4y = 7 14y = 7 y = 1/2 = .5
4x-10y=11 4x=11+10y 10y+11=4x 10y=4x-11 y=(4/10)x-(11/10) y=(2/5)x-(11/10)

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
Y-8x plus 9y equals 10y-8x.
The points are: x = 0 and y = -1/10.
Basically, the x-intercept is what x equals when y=0, and the y-intercept is what y equals when x=0. To find the x intercept, set y equal to 0. -5x+10(0)=20 -5x+0=20 -5x=20 divide both sides by -5 x=-4 so the x intercept is (-4,0) To find the y intercept, set x equal to 0. -5(0)+10y=20 0+10y=20 10y=20 divide both sides by 10 y=2 so the y intercept is (0,2)
10y = 9y + 4, so y = 4
