Question

What is the answer of equation 9x(30+7)=(9x30)+(9x7)

Answer 1

9x(30+7)=(9x30)+(9x7)

remove parenthesis :

9x(30+7) = 9x * 30 + 9x * 7

multiply : 9 * 30 = 270

9x(30+7) = 270x + 9 * 7x

multiply : 9*7 = 63

9x(30+7) = 270x +63x

add : 270x + 63x = 333x

expand : 30 + 7 = 37

multiply : 9*37 = 333x

subtract : 333x - 333x = 333x - 333x

Answer : 0

I hope this helps
