Let's let the number be represented by the variable x.
The equation can be written as:
4x - 4 = 8
To solve this equation, we need to isolate the variable x.
Adding 4 to both sides of the equation:
4x - 4 + 4 = 8 + 4
4x = 12
Dividing both sides by 4:
4x/4 = 12/4
x = 3
Therefore, the value of the number is x = 3.
Write an equation and solve: Four times a number, decreased by 4 is 8
