Answer:

r=-29/20

Step-by-step explanation:

because

-2 1/4 will be -9/4=r-2/5 now you add 2/5 to both sides

witch means you have to increase the denominator to the greatest common denominator of 4 and 5 witch is 20 multiply the number used to combine with the denominator to get 20 to the numerator so itll be -45/20+16/20 witch will be -29/20 so there fore r=-29/20 or 1 9/20.
