i'm not the greatest at algebraic expressions.

Thank you for the opportunity to help you with your question!

assuming that your expression 2x + 7(3x) is equal to 0

then opening the parenthesis will give us;

2x + 21x = 022x = 0

2x + 21x = 0

22x = 0

dividing both sides of the equation above by 22;

22x/22 = 0/22

then the value of x = 0

I hope i served you well.

Thank you.
