If 3/5 ᵗʰ of a number is 4 more than 1/2 the number, then what is the number?

Step-by-step explanation:

3/5 x = 1/2 x + 4                             Subtract 1/2 x from both sides

3/5 x - 1/2 x  = 1/2 x - 1/2 x + 4      Change the left side to fractions with LCDs

6/10 x - 5/10 x = 4                          Subtract

1/10 x = 4                                          Multiply both sides by 10

10* 1/10 x = 4 * 10

x = 40
