Answer:
The expression 3x + 10 can be written on the right hand side of the equation
Explanation:
For the equation to have no solution, it must be that the terms in x is equal on both sides and also that the number term in both sides is unequal
If the number term is equal with the x term being same, then what we have is a set with infinite solution
So in this case, let us write the term on left fully
That would be;
3x + 3 + 9
= 3x + 12
So any term on the right should be 3x added to any other number other than + 12
So that could be;
3x + 10
