-6 - 10y = -10
Add 6 to both sides: -10y = -4
Divide both sides by -4: y = -4/-10 = 4/10 = 0.4
Check by putting the value back into the equation: -6 - (10 x 0.4) = -6 -4 = -10
The points are: x = 0 and y = -1/10.
10y = 5 y = 5/10 Therefore, y = 0.5
Oh, dude, let's break it down. So, if x equals 6 and y equals 8, we just plug those values into the expression. 9 times 6 is 54, and 10 times 8 is 80. Add those up, and you get 134. Ta-da!
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
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
what is the solution of x-5y=10 and 2x-10y=20
The points are: x = 0 and y = -1/10.
10y = 5 y = 5/10 Therefore, y = 0.5
4x-10y=11 4x=11+10y 10y+11=4x 10y=4x-11 y=(4/10)x-(11/10) y=(2/5)x-(11/10)

10y= 6y+5+3y 10y=6+9y y=6
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
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
10 is.
18 + 70 ie 87
y - intercept = 10x - intercept = -10y- intercept: x = 0y = x + 10y = 0 + 10y = 10x - intercept: y = 0y = x + 100 = x + 10x + 10 = 0x = -10
10y + 8y = 18y = 15 y = 15/18 y = 5/6 = 0.833333.....
