Answer:
-19/9
Step-by-step explanation:
First, you would plug in the numbers for y and r. Therefore, your equation should now be 5 = 9x + 24. Now you would put like terms on the same side. It now then look like -19 = 9x. You divide by 9 to get the x by itself. The answer should be x = -19/9.
The answer is 7 7/8 because 5 1/4 times 1 1/2 is 7 7/8. I hope this answers your question.
