Question 565090
Let us call the "number" x.
Four times the number is 4 times x, or 4x.
Three times the number is 3 times x, or 3x.
Three times the number increased by nine is 3x + 9.
Therefore, your equation is 4x = 3x + 9.
Subtract 3x from both sides of the equation.
1x = 9, or x = 9
As a result, the number is 9.
Good luck! =)
