Answer:
6
Step-by-step explanation:
The orange line doesn't pass 6, it stays at 6.
Step-by-step explanation:
Commutative means a + b = b + a
So, 4x + 3 = 3 + x
Associative means a + (b + c) = (a + b) + c
So, 6 + (9 + 7) = (6 + 9) + 7
Distributive means expand the bracket a * (b + c) = a*b + a*c
So, (4x + 3y + 2z) * 7 = 4x*7 + 3y*7 + 2z*7
Commutative is a + b = b + a
So, 15a + 15b = 15b + 15a
