Question

why is 16-8a+b=8a-b=16 why its not 8a+b=16
pls tell me ​

Answer 1

Step-by-step explanation:

it is 8a-b=16 because in 16-8a+b if we move 8a and b after the equals to marks then the sign changes if there will be '-'then it will turn into '+'.

And there is -8a+b so it will change to 8a-b because of change in sign.
