Answer:

x = 2, y = 5

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, thus

PT = TR and QT = TS

Substitute in values

y = 2x + 1 → (1)

3y = 3x + 9 → (2)

Substitute y = 2x + 1 into (2)

3(2x + 1) = 3x + 9

6x + 3 = 3x + 9 ( subtract 3x from both sides )

3x + 3 = 9 ( subtract 3 from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

Substitute x = 2 into (1)

y = 2(2) + 1 = 4 + 1 = 5

9/20 + 2 9/10 or nine twentieths plus two and nine tenths
seropon [69]

So, first we have to put in an equation

9/20+ 2 9/10

multiply 9/10 by 2

So you get 9/20+ 2 18/20

Add the fractions together and you'll get 26/20

since their isn't a whole number a whole number it's just 2 and 26/20 reduce it to

2 and 9/5

I hope this is right. This is how I was taught.
