Solution 1

Sure, let's solve these simultaneous equations step by step using the substitution method.

The given equations are:

  1. r = t + 5
  2. r + 3t = -7

Step 1: From equation (1), we know that r = t + 5. We can substitute this into equation (2) to eliminate r.

Step 2: Substituting r in equation (2), we g Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
