What is the solution to the system of equations?

(7, 13/3)

Step-by-step explanation:

  Line up the equations on top of each other

  Multiply the top equation by in order to cancel out the variable

  Switch out the first equation for this one

  Line up the equations

  Add the two equations top to bottom, left to right

Now that you've found , you need to find . Just plug in the y-value to either of the equations in Step 1:

The first equation has smaller numbers, so let's use that one.

To make it easier you can multiply all the terms in the equation by 3:

The - and - values together give a solution of ( , )

what are the statements

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".
