Answer 2

To solve the equation X + 2 1/7 = 3, we need to isolate the variable X on one side of the equation. Here's how you can solve it step by step:

Step 1: Convert the mixed fraction 2 1/7 to an improper fraction. The whole number 2 can be written as 14/7, so the equation becomes X + 14/7 + 1/7 = 3.

Step 2: Combine the fractions with a common denominator. In this case, the common denominator is 7. The equation now becomes X + (14 + 1) / 7 = 3, which simplifies to X + 15/7 = 3.

Step 3: To get rid of the fraction, multiply the entire equation by 7 to clear the denominator. This gives us 7(X + 15/7) = 3 * 7.

Step 4: Simplify the equation by distributing 7 to the terms inside the parentheses. This results in 7X + 15 = 21.

Step 5: Subtract 15 from both sides of the equation to isolate the variable X. This gives us 7X = 21 - 15, which simplifies to 7X = 6.

Step 6: Divide both sides of the equation by 7 to solve for X. This yields X = 6/7.

Therefore, the solution to the equation X + 2 1/7 = 3 is X = 6/7.
