Question

3a+7b+9c-a-b+3c I cannot understand

Answer 1

Heya friend,


3a + 7b + 9c - a - b + 3c

We only solve like terms.

So, arrange them and then solve.

3a - a + 7b - b + 9c + 3c

= 2a + 6b +12c.

Now it is unlike terms so we cannot solve it.

Hence, the required answer is 2a + 6b + 12c.

Thanks

Hope it helps you.
