Let's call the number x.
The equation can be written as:
4x - 4 = 8
To solve for x, let's add 4 to both sides:
4x - 4 + 4 = 8 + 4
This simplifies to:
4x = 12
Next, let's divide both sides by 4 to isolate x:
4x/4 = 12/4
This gives us:
x = 3
Therefore, the solution is x = 3.
Write an equation and solve: Four times a number, decreased by 4 is 8.(1 point)
