For the parallelogran, find the value of the variables. show your work

Parallelogram, opposite sides are equal

So

5x + 2 = 17

5x = 15

x = 3

and

3y - 6 = 21

3y = 27

y = 9

x = 3 and y = 9

Opposite sides of a parallelogram are equal to each other

therefore make the opposite sides equal to each other in an equation.

====================================================================

We'll have 2 equations:

3y - 6 = 21 and 5x + 2 = 17

====================================================================

Solve the first equation

3y - 6 = 21

Add 6 to both sides

3y = 27

Divide both sides by 3

y = 9

____________________________________________________________

Solve the second equation

5x + 2 = 17

Subtract 2 from both sides

5x = 15

Divide both sides by 5

x = 3

$12. that is my answer.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
