3y = 12 - 5x
12 - 5x = - 5x + 3
- 5x + 12 = - 5x + 3
NO solution

there's no need to substitute anything when you move 5x to the left side in the second equation you have the same coefficients of x and y for both equations but a different answer for each. So its easy to see there is no solution that will satisfy both equations.

no solution.
once you substitute 3y into the equation and combine like terms you end up with 3=12, which isnt true.

change the second equation to: 5x + 3y = 3
then use subtraction method to get 0=9
because this is not true, the answer is no solution

you may also write the two equations in the slope intercept form. you will see that these are two lines with the same slope but different y-intercepts and are therefore parallel and do not intersect.
therefore the system has no solution.

these equations are equations to two parallel lines.they intersect at no point. so there is no solution.
