2x plus 3y
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
The equation for 3y + 3y = -1 is 3y + 3y = -1.
-2x plus 3y equals 1
x = 8, y = -1
Technically, the answer is probably YES, but it is a tautology and, therefore, adds no value.
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
It cannot be factored.
