Standard form = Ax + By = c
a.
y + 1 = x
Subtract 1 from both sides.
y = x - 1
Subtract x from both sides.
-x + y = 1
b.
2y = -6 + 2x
Subtract 2x from both sides.
-2x + 2y = -6
c.
2x + 4y = -3
This equation is already in standard form.
d.
-12x - 9 = -6y
Add 6y to both sides.
-12x + 6y - 9
Add 9 to both sides.
-12x + 6y = 9
e.
-2y - 4 = -3x
Add 3x to both sides.
3x -2y - 4
Add 4 to both sides.
3x - 2y = 4
f.
-4y = 10
Because there is no x value, nothing more needs to be done to this equation.
