Which of the following is not a step used to solve multi-step equations? a. identify values of variables in the equation from the written word problem b. finish by getting all variables and constants on the same side of the equation c. plug in known variables from the word problem into the equation d. translate the written phrases into an algebraic equation

hey i’m new i won’t be answering any questions now bye peeps see you next time

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".
