The correct Answer is:
To solve the equation \(\frac{7t + 13}{15} + 7 \left(\frac{2t - 1}{5}\right) = 6\), we will follow these steps: ### Step 1: Simplify the equation Start by rewriting the equation: \[ \frac{7t + 13}{15} + 7 \cdot \frac{2t - 1}{5} = 6 \] ### Step 2: Simplify the second term Multiply \(7\) with \(\frac{2t - 1}{5}\): \[ 7 \cdot \frac{2t - 1}{5} = \frac{7(2t - 1)}{5} = \frac{14t - 7}{5} \] ### Step 3: Rewrite the equation Now substitute this back into the equation: \[ \frac{7t + 13}{15} + \frac{14t - 7}{5} = 6 \] ### Step 4: Find a common denominator The common denominator for \(15\) and \(5\) is \(15\). Rewrite the second term: \[ \frac{14t - 7}{5} = \frac{3(14t - 7)}{15} = \frac{42t - 21}{15} \] ### Step 5: Combine the fractions Now combine the two fractions: \[ \frac{7t + 13 + 42t - 21}{15} = 6 \] This simplifies to: \[ \frac{49t - 8}{15} = 6 \] ### Step 6: Eliminate the fraction Multiply both sides by \(15\) to eliminate the fraction: \[ 49t - 8 = 90 \] ### Step 7: Solve for \(t\) Add \(8\) to both sides: \[ 49t = 90 + 8 \] \[ 49t = 98 \] Now, divide both sides by \(49\): \[ t = \frac{98}{49} = 2 \] ### Final Answer The value of \(t\) is \(2\). ---
