What is a possible "solution" for this inequality. X > 7

X = -7?

X = -19?

X = 19?

I was absent the day we learned this and ny teacher won't explain it to me, thats all that i was given. Basically which one of the three would be a solution for X > 7
I tried to do it but she said my method was wrong so i need some help please!

answer: i believe c. is the answer sorry if i am wrong

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

you need to give us more information since we can't answer
