Question

Substract the second expression from the first in the following

6a+b-9c-6a-7b+3c​

Answer 1

a - 6b - 6c

Step-by-step explanation:

Okay so we are subtracting the first expression from the second which would be (6a + b - 9c) - (-6a - 7b + 3c)

so you would subtract the a expressions from each other, the b expressions from each other and the c expressions from each other it would be:

6a - 6a = a

b - 7b = - 6b

3c - 9c = -6c

now we put it back into the expression which would be :

a - 6b - 6c

Hope this helps you
