This question does not make sense. There cannot be that many equal signs.
x + 3x + 3x = 3
x = 3/7
When you multiply the first equation by 3, you get:
3 × 3x = 9x
3 × y = 3y (but when added, that part gets eliminated)
3 × 3 = 9
So you end up with
9x + 3y = 9
x - 3y = -2
(add)
10x = 7
So your answer is B. 10x = 7. I hope this helps!
