One solution for -3x - 2y = 4 is:
-3x - 2y = 4
-3x = 4 + 2y
-3x/3 = (4 + 2y)/3
-x = 2/3y + 1 1/4
x = -2/3y - 1 1/4
x=2
1). y = 12). y = -4x3). y = -12xA "solution" is a pair of numbers ... one for 'x' and one for 'y' ... that makes the statements true.There is no solution for the group of all three equations.The solution for #1 and #2 taken together is (-1/4 , 1).The solution for #1 and #3 taken together is (-1/12 , 1).The solution for #2 and #3 taken together is (0, 0).
Yes, x =7 and y = 4 is one of many solutions, if that is the only equation given.
It is (-1, 3).
