y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
3x + 2 = -10 3x = -12 x = -4
all you do is subtract the 3x from both sides and you get:y = -3x + 12
6-3x+12=0 6+12-3x=0 18-3x=0 18=3x x=6
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4

x = 3 and y = 2
x = 0
3x-5=3x+5 There is no solution.
Both of them are equations!The solution is (x, y) = (2, 1).
If: 3x+6 = 12 Then: x = 2
2x-12
3x+8 = 12 3x = 4 x = 4/3
3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
Point slope equation: Y=3X+12
3x+12=x+48: 3x-x=-12+48 2x=36 x=18
