Let's represent the number with the variable x. The given information states that "Four times a number, decreased by 4 is 8". Mathematically, this can be written as:
4x - 4 = 8
To solve for x, we will isolate it by moving the constant term (-4) to the other side of the equation:
4x = 8 + 4
Combining like terms, we get:
4x = 12
Finally, we divide both sides by 4 to solve for x:
x = 12/4
Simplifying the right side of the equation, we find:
x = 3
Therefore, the solution to the equation is x = 3.
Write an equation and solve: Four times a number, decreased by 4 is 8.(1 point)
