Question
Solution 1
The ordered pairs (a+2,4) and (5, 2a+b) are equal. This means that the x-coordinates are equal and the y-coordinates are equal.
So, we can set up the following equations:
a + 2 = 5 4 = 2a + b
Solving the first equation for a, we get a = 5 - 2 = 3.
Substituting a = 3 into the second equation, we Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
