Let's say the number is x. According to the problem, we can then write the equation as:
4x - 4 = 8
Now let's solve for x:
Add 4 to both sides of the equation:
4x - 4 + 4 = 8 + 4
Simplifying:
4x = 12
Divide both sides by 4 to isolate x:
4x/4 = 12/4
Simplifying:
x = 3
So the number is 3.
Write an equation and solve: Four times a number, decreased by 4 is 8. (1 point)
