-3y + 4 = -1
Add 3y to each side:
4 = -1 + 3y
Add 1 to each side:
5 = 3y
Divide each side by 3:
y = 5/3
The equation for 3y + 3y = -1 is 3y + 3y = -1.
-2x plus 3y equals 1
2x plus 3y
Technically, the answer is probably YES, but it is a tautology and, therefore, adds no value.
y = -1
y=4
It cannot be factored.
(5, 1)
(-1, 0)
(1, 1)
2x + 3y = 1 y = 1/3 - 2x/3
second equation x 2: 4x + 6y = 4 subtract first equation: 9y = 3 so y = 1/3 and x = 1/2
