I don't know how to write these 2 sentences.

One number is twice another number. Twice the lesser number increased by three times the greater number is 75

a = 2b

2a+3b = 75

To write these two sentences, you need to follow the given information and express it in a clear and concise manner. Let's break it down step by step:

1. One number is twice another number.
This means that one number is double the value of another number. Let's call the lesser number "x" and the greater number "y". To write this sentence, you can say:

"The greater number, y, is twice the value of the lesser number, x."

2. Twice the lesser number increased by three times the greater number is 75.
This means that if we take two times the value of the lesser number and add three times the value of the greater number, the result is 75. Using the same variables, x and y, we can express this sentence as follows:

"2x + 3y = 75."

By combining these two sentences, we have:

"The greater number, y, is twice the value of the lesser number, x. Additionally, if we take two times the value of x and add three times the value of y, the result is 75, expressed as 2x + 3y = 75."

Remember, it's important to understand the given information and use the appropriate variables to clearly express the relationship between the numbers.
