3ab,-4ab, 7ab, -5ab​

Answer 1

Step-by-step explanation:

3ab + 4ab + 7ab = 0

Combine like terms: 3ab + 4ab = 7ab

7ab + 7ab = 0

Combine like terms: 7ab + 7ab = 14ab

14ab = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Divide each side by '14'.

ab = 0

Simplifying

ab = 0
