Question 60163
Hello Lyn,


8x - 5 + 9x = 17x - 5 


We need to prove that left hand side is equal to right hand side.


This can be written by adding the like terms. 


First grouping them and then adding, we get: 


8x + 9x - 5 


Adding the like terms, we get: 


17x - 5


Hence, the required answer.
