Answer 2

To solve for x in the equation $\frac{3}{4}x + \frac{5}{14}x - \frac{10}{21}x = \frac{1}{7}$, follow these steps:

Step 1: Find a common denominator for the fractions on the left-hand side. The least common multiple of 4, 14, and 21 is 84.

Step 2: Rewrite the fractions with the common denominator:

$\frac{63}{84}x + \frac{30}{84}x - \frac{40}{84}x = \frac{1}{7}$

Step 3: Combine the fractions on the left-hand side:

$\frac{53}{84}x = \frac{1}{7}$

Step 4: Solve for x by isolating it on one side of the equation. Multiply both sides of the equation by $\frac{84}{53}$:

$x = \frac{1}{7} \cdot \frac{84}{53}$

Step 5: Calculate the value of x:

$x = \frac{12}{53}$

So, the solution to the equation is $x = \frac{12}{53}$.
