A number equals four less than three times the number. What is the number?
x = 3x - 4
x - 3x = -4
-2x = -4
x = -4/-2
x = 2
To find the number that satisfies the given condition, we can use an algebraic approach. Let's call the number "x."
According to the given condition, the number equals four less than three times the number, which can be expressed as:
x = 3x - 4
To solve this equation for x, we can follow these steps:
1. Simplify the equation by combining like terms:
x = 3x - 4
Rewrite as: x - 3x = -4
Simplify: -2x = -4
2. Divide both sides of the equation by -2 to isolate x:
-2x / -2 = -4 / -2
Simplify: x = 2
Therefore, the number that satisfies the condition is x = 2.
