3x-y=9 y=3x-9
If x equals the square root of ...., then you already have solved for x
y = 3 (y^3)(y^3 - 1) = (3^3)(3^3 - 1) = 27(27 - 1) = 27(26) = 702
It is a linear equation in two variables

y = -35
If: 23.64 = y-8.31 Then: y = 31.95
the y-1 is a minus .
x = 4 and y = 7
3x-y=9 y=3x-9
y equals 3
Y=-1
-96 = 33-y -96-33 = -y -129 = -y y = 129 Remember a minus divided into a minus is equal to a plus.
x = 4 and y = 7 which will satisfy both equations
No, y=x-2 is linear.
