Question

I need help on parallelograms.

Answer 1

y=15

5y-20=2y+25 move terms

5y-2y = 25+20 calculate like terms

3y=45 divide both sides by 3

Answer 2

You would make the equation 5y-20=2y+25 and then solve

You would add both sides by 20

5y=2y+45

Then you would add both sides by -2y

3y=45

finally you will multiply both sides by 1/3 and get 15 as Y

y=15
