K = k + 1378 Cross multiply: K * 8 = 7 * k + 13 Simplifying K * 8 = 7 * k + 13 Reorder the terms for easier multiplication: 8K = 7 * k + 13 Reorder the terms: 8K = 7 * 13 + k 8K = 13 * 7 + k * 7 8K = 91 + 7k Solving 8K = 91 + 7k Solving for variable 'K'. Move all terms containing K to the left, all other terms to the right. Divide each side by '8'. K = 11.375 + 0.875k Simplifying K = 11.375 + 0.875k
