Solution 1

Sure, let's solve these equations step by step.

First, let's rewrite the first equation to express r in terms of t:

4t = r + 5

Subtract 5 from both sides to isolate r:

r = 4t - 5

Now, let's substitute r in the second equation with 4t - 5:

t - 4(4t - 5) = 20

Simplify the equation:

t - 16t + 2 Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
