x = 1
(5, 1)
The slope is -1. 3x+3y=12 Subtract 3x 3y=-3x+12 Divide by 3 y=-x+4
(2, -1)
3x-1 = 11 3x = 11+1 3x = 12 x = 4 Therefore: x2+2 = 18
3x-1=11 3x = 12 x = 4 Then, x^2 +x = 20.
y = 3x + 1
y = 3X - 1
3x-1 = 11 3x = 11+1 = 12 x = 12/3 = 4 Therefore: x2 + 2 = 16 + 2 = 18
3x + 6y = 12 Rearranging terms: 6y = -3x + 12 Divide through by 6: y = -1/2*x + 2
If: 3x+5 = 4x+1 Then: x = 4
Both of them are equations!The solution is (x, y) = (2, 1).
