Question

4 Solve the following equations and verify their solutions.
9-r/5=3-r​

Answer 1

Answer:

=> 9-r = 15 - 5r

=> 9 - 15 = -5r + r

=> -6 = -4r

=> r = 2/3

Answer 2

Step-by-step explanation:

9-r/5 = 3-r

9-r = 15-5r

4r = 6

r = 6/4

r = 3/2

verification :-

put r = 3/2

9-r/5 = 3-r

9-r = 15 - 5r

9-3/2 = 15 - 5(3/2)

15/2 = 15/2

LHS = RHS

hence, verefied.
