You need to spell out mathematical operations in your question, or they will come out as above, ambiguously. Use plus, minus, times, divided by, and any other operations you want in your equations.
3x-y=9 y=3x-9

f(x) = 3x + 9 y = 3x + 9 so 3x = y - 9 x = y/3 - 3 Therefore, the inverse function is g(x) = x/3 - 3
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
-9
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
-9
y = 3x + 2 y-2 = 3x x = (y-2)/3 So the inverse is (x-2)/3
y = 3x + 8Replace x with y and y with x.x = 3y + 8Solve for y.x - 8 = 3y3y = x - 8y = (x-8)/3
3x-y = 9 2x+y = 6 Add both equations together: 5x = 15 x = 3 and y = 0
your equation is y=3x + 4 here are five parallel equations... y=3x + 5 y=3x + 6 y=3x + 7 y=3x + 8 y=3x + 9
