3x+12x = 15 15x = 15 x = 1
7x + 16 = 3x + 4 4x = -12 x = -3
3x + 4 = 16 3x = 16 - 4 x = 12/3 x = 4
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
3x + 16 = 22 3x = 6 x = 6/3 x = 2
If: 3x+y = 16 Then: y = -3x+16 whereas -3 is the slope and 16 is the y intercept
x=5
3x - 2 + 5 = 16 3x + 3 = 16 3x = 13 x = 13/3 ~ 4.333
