yes 3xy=6

x = -1 y = 2 2x3 - 3xy = 2 (-1)3 - 3(-1)(2) = 2 (-1) - (-6) = -2 + 6 = 4 Suggestion: Please be careful around problems like this until you have some more experience.
The solutions to the quadratic equation are: x = -1 and x = 6
like 6+6+6+6=24
[x + y = 6] has an infinite number of solutions.
Two solutions and they are:- x = 0 and y = 3
yes
4+2=6 Four plus two equals six.
Just one.
24 divided by three equals 8 divided by four equals 6 2 plus 4 equals 6
3xy-2y=0 3xy=2y y=2y (3x) y/2y=3x 1/2=3x multiply across by 2 1=6x 1/6=x therefore substituting x=1/6 into 3xy-2y; 3(1/6)y-2y=0 1/2y=2y y=2y/0.5 0.5 aka 1/2 y=1
