-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
-2x plus 3y equals 1
second equation x 2: 4x + 6y = 4 subtract first equation: 9y = 3 so y = 1/3 and x = 1/2
y = -1
(-1, 0)
2x + 3y = 1 y = 1/3 - 2x/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.
second equation x 2: 4x + 6y = 4 subtract first equation: 9y = 3 so y = 1/3 and x = 1/2
y = -1
-2x + 3y = -7 3x + y = 16 simultaneous equations. Elimination a letter. Arbitrarily select 'y' Hence multiply the bottom eq'n by ' -3' Hence -2x + 3y = -7 -9x - 3y = -48 Add the eq'ns/ -11x = =55 x = -55/-11 = 5 When x = 5 , substitute into either eq'n for 'y' -2(5) + 3y = -7 -10 + 3y = -7 3y = 3 y = 1 Hence answer in ( x,y) fpr, is ( 5,1).
(-1, 0)
2x + 3y = 1 y = 1/3 - 2x/3
y=4
It cannot be factored.
