16x2+12x+18=3x=2x2+6x+9=3x=
sorry i try
No, the graphs of the lines are not parallel because if you simplify 27x-3y=-81, you get y=9x+27, and in order to have the lines parallel, both equations must have the same "m" in y=mx+b. 6 and 9 do not equal, so no they are not parallel.
The first step to solving your equation would be to subtract 6.4 from both sides.
<span>3.5n+6.4=42.5
Subtract 6.4
3.5n=42.5</span>
