"five times a number subtracted from 40 is the same as three times the number. " translates to 40-5x=3x



40-5x=3x Start with the given equation.


-5x=3x-40 Subtract 40 from both sides.


-5x-3x=-40 Subtract 3x from both sides.


-8x=-40 Combine like terms on the left side.


x=%28-40%29%2F%28-8%29 Divide both sides by -8 to isolate x.


x=5 Reduce.

Answer:

So the solution is x=5


So the number is 5
