3y = 4x + 9 -4x + 3y = 9 is the standard form
4x - 11 = 0
-3
-4x + 3y = 9
In standard form it is 4x - 4y = 6 or 2x - 2y = 3
4x + y = 10 is a perfectly valid functional form. The standard form is 4x + y - 10 = 0
3y = 4x + 9 -4x + 3y = 9 is the standard form
-3
4x - 11 = 0
-3
-4x + 3y = 9
In standard form it is 4x - 4y = 6 or 2x - 2y = 3
The standard form, which is the form that can be generalised to 3 or more dimensional spaces, is 4x + 5y - 13 = 0
You're there. 4x = 10y - 8.[so subtract 10y from both sides, 4x - 10y = -8]multiply b.s. by -1 , gives -4x +10y = 8
4x-y+7=0
y=-x^2+4x-3
x = 4.5
