Solving the Equation: 2x 1.2 and Exploring Pairs of Numbers That Sum to 1.2

In this article, we will focus on how to solve the equation 2x 1.2 through various methods and also explore the possibilities of pairs of numbers that add up to 1.2. Learning to solve such equations and understand the relationships between numbers can be very beneficial in mathematical problem-solving.

Solving 2x 1.2

To find the number x that satisfies the equation 2x 1.2, follow these steps:

Set up the equation: 2x 1.2 Divide both sides of the equation by 2:

[ x frac{1.2}{2} ]

Calculate the result:

[ x 0.6 ]

Thus, the number x is 0.6.

Interpretations and Other Pairs of Numbers That Sum to 1.2

While 0.6 is the solution to the equation, there are many pairs of numbers that add up to 1.2. Let's explore some of these pairs for further understanding:

0.1 and 1.1 0.2 and 1 0.3 and 0.9 0.4 and 0.8 0.5 and 0.7

Mathematical Notations and Representations

Let the first number be a_1 and the second number be a_2. Here are a few notations and their meanings:

Left{begin{matrix}a_11.2a_21.2end{matrix}Right. Assume a certain number is X, and twice the number is 2X. Therefore, 2X 1.2, and X 0.6. 2x0.6 1.2, so the number is 0.6. If the point (. ) means multiplication, the number is 1, since 1x2 2 and 2x1 2.

Conclusion

To summarize, solving the equation 2x 1.2 leads us to the conclusion that the number is 0.6. This problem highlights the importance of proper notation and understanding the implications of different pairings of numbers.
