Define a variable and write a equation to find each number. Then solve.
A number equals six less than four times a number. What is the number?
2x +y = 36
X- y = 9
x = 4x-6
...
45 -4
To solve this problem, let's define a variable to represent the unknown number. Let's call it "x."
The equation can be written as:
x = 4x - 6
To solve for x, we need to isolate it on one side of the equation. Here's how we can do that:
x - 4x = -6 (subtract 4x from both sides)
-3x = -6 (combine like terms)
x = (-6) / (-3) (divide both sides by -3)
Simplifying further, we have:
x = 2
Therefore, the number is 2.
