3x%2B4=7x%2B46 Start with the given equation.


3x=7x%2B46-4 Subtract 4 from both sides.


3x-7x=46-4 Subtract 7x from both sides.


-4x=46-4 Combine like terms on the left side.


-4x=42 Combine like terms on the right side.


x=%2842%29%2F%28-4%29 Divide both sides by -4 to isolate x.


x=-21%2F2 Reduce.

Answer:

So the solution is x=-21%2F2
