-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
18 + 70 ie 87
