Jill is thinking of a number. Four more than three times the number is thirteen. What is the number?(1 point)
Jill's number is (Fill in the blank)
To find the number that Jill is thinking of, we can use algebra.
Let's assume the number Jill is thinking of is represented by the variable "x".
According to the given information, four more than three times the number is thirteen. This can be written as:
3x + 4 = 13
Now, we can solve this equation to find the value of x.
Subtracting 4 from both sides of the equation:
3x + 4 - 4 = 13 - 4
3x = 9
Dividing both sides of the equation by 3:
3x/3 = 9/3
x = 3
Therefore, Jill's number is 3.
