Question

Write an equation and solve: Four times a number, decreased by 4 is 8.(1 point)

Answer 1

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.
