Help with a 7th grade problem. How do I solve for x
4x = y

Y/4

Step-by-step explanation:

Well, you need to isolate x so you can figure out what it is. So, divide 4x by 4 to get rid of the 4. What you do to one side, you must do to the other. So, divide y by 4, and since we do not have the value for y, the answer is quantity y divided by 4.

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".
