Remark

In order for the figure to be a parallelogram, the 2 parts of the same diagonal must be equal.

Equation

Therefore 79 - y = 2y + 22         Add y to both sides.

Solution

79 = 2y + y + 22                          Combine

79 = 3y + 22                                 Subtract 22 from both sides

79 - 22 = 3y                                 Combine like terms

57 = 3y                                         Divide by 3 on both sides

57/3 = y                                        Divide

19 = y

Answer y must be 19

Edit

For x you would have to obey the same principle.

3x + 1 = x + 27      Subtract x from both sides

3x - x + 1= 27       Combine like terms

2x + 1 = 27            Subtract 1 from both sides

2x= 27 - 1             Combine the right

2x = 26                Divide by 2 on both sides.

2x/2 = 26/2  

x = 13

I am pretty sure y would be 79

"of" means multiply      and         "is" means equal

1. \frac{1}{3}x = 14

                                x = 14(3)      <em>multiply both sides by 3 to isolate "x"</em>

                                x = 42

2. \frac{1}{5}x = 14

                                x = 14(5)      <em>multiply both sides by 5 to isolate "x"</em>

                                x = 70

3. \frac{2}{5}x = 14

                                2x = 14(5)      <em>multiply both sides by 5 </em>

                                2x = 70

                                  x = 35         <em>divide both sides by 2 to isolate "x"</em>

4. \frac{7}{8}x = 14

                                7x = 14(8)      <em>multiply both sides by 8 </em>

                                7x = 112

                                  x = 16         <em>divide both sides by 7 to isolate "x"</em>
