HELP ASAP PLEASE!! 1+y= 2
y=-12+3
1.in two or more complete sentences, explain how to solve the system of equations algebraically
2.solve the system of equations. in your final answer, include all of your work.

1+y= 2

y = 2 - 1

y = 1

y=-12+3

y = -9

Step-by-step explanation:

first you rewrite the question, then you group like terns.

After that you do the needful operation example; if the question is asking you to add or subtract or divide or multiply.

later, you write your final answer down.

hope it helps .

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".
