The Deep Dive

To solve the equation \( \frac{2(x+1)}{5}-\frac{3(x-1)}{10}=\frac{7 x+1}{10} \), start by getting a common denominator. The common denominator for the fractions is 10. Rewrite each term: \[ \frac{4(x+1)}{10} - \frac{3(x-1)}{10} = \frac{7x + 1}{10} \] Now, combine the left side fractions: \[ \frac{4(x+1) - 3(x-1)}{10} = \frac{7x + 1}{10} \] Distributing on the left side: \[ \frac{4x + 4 - 3x + 3}{10} = \frac{7x + 1}{10} \] This simplifies to: \[ \frac{x + 7}{10} = \frac{7x + 1}{10} \] Since both sides have a common denominator, we can equate the numerators: \[ x + 7 = 7x + 1 \] Now, rearranging the equation: \[ 7 - 1 = 7x - x \] This gives: \[ 6 = 6x \] Now, solve for \( x \): \[ x = 1 \] Thus, the solution to the equation is \( x = 1 \).
