2-2y+3(1)=7 solve for y

Question

It is an assignment for homework for school and i can figure it out.          

Answer 1

Hi Maria from Houston, TX...hope you're having a great weekend.

To begin with, I have a question about your problem. What is the expression:   (1)

   if (1) is simply one times the expression     2 - 2y + 3 then begin with combining like terms:

                    2 - 2y + 3(1) = 7     Start with combining like terms.

                    2 + 3(1) - 2y = 7     Complete the operation if (1) is times 1

                    2 + 3 - 2y = 7         Next operation

                    5 - 2y = 7               Next, let's move the known values and

                                                   the unknown values to either side of 

                                                   equal sign. Notice that the y value is

                                                   looking like a negative value which can

                                                   cause some confusion. So consider this

                    5 - 2y = 7               Try to keep the y value a positive value

                      + 2y =   + 2y        Add the y value to each side

                    5 + 0  =  7 + 2y      Rewrite the equation

                    5        =   7 + 2y     Next move 7 to other side of = sign

                        - 7     - 7             Complete operation

                   5 - 7  =  2y              Now its your turn to complete the rest.

Let me know if you need any further help

Answer 2

2 - 2y + 3(1) = 7

2 - 2y + 3 = 7

5 - 2y = 7

-2y = 2

y = -1
