Understanding the Math Mystery: How 70__100

The equation "70__100" may seem mysterious at first glance, but through a series of logical steps, we can unravel its mystery and understand its solution. This article will break down the problem and provide a step-by-step explanation, making it accessible for readers with different levels of mathematical expertise.

Solving the Equation by Direct Calculation

Let's take a look at the problem in two different ways and see how we can resolve it.

Method 1: Using Simple Subtraction

One straightforward approach is to directly subtract 70 from 100. This is a great way to visualize the missing value.

100 - 70 30

So, to make the equation true, we need to add 30 to 70, resulting in 100. This can be represented mathematically as:

70 30 100

Method 2: Solving the Equation Algebraically

Let's approach the problem algebraically. We'll set up the equation and solve for the unknown value X.

Step 1: Setting Up the Equation

We start with the equation: 70 X 100

Step 2: Isolating the Unknown Value

To find the value of X, we need to isolate it on one side of the equation. We can do this by subtracting 70 from both sides of the equation:

X 100 - 70

Performing the subtraction, we get:

X 30

Step 3: Converting the Value to a Decimal

If we want to express the value of X as a decimal, we can divide 30 by 100:

X 30 / 100 0.30

So, the value of X is 0.30, or 30%.

Conclusion

In both methods, we find that the missing value is 30. Whether we solve it through simple subtraction or algebraic manipulation, the result remains the same. This example demonstrates the process of solving basic equations and understanding percentages, making it a valuable learning tool for anyone interested in improving their mathematical skills.
