Question

what should be added to 2a+7b to get -17a-3b​

Answer 1

Answer:

-19a-10b

Step-by-step explanation:

Let the no. be x

2a+7b + x = -17a-3b

x = -17a-3b -2a-7b

x = -17a-2a-3b-7b = -19a-10b

Hence the no. is -19a-10b

VERIFICATION

2a+7b + (-19a-10b) = -17a-3b

2a+7b - 9a-10b = -17a-3b

2a-19a+7b-10b = -17a-3b

-17a-3b = -17a-3b
