Mathematics

y =2

x =3

Step-by-step explanation:

Given

The attached parallelogram

Required

Find x and y

Opposite sides are equal

So:

$PQ = SR\ and\ QR = PS$

This gives:

2y + 3 = y + 5 -- (1)

4x - 3 = 4y + 1 -- (2)

2y + 3 = y + 5

Collect like terms

2y - y= 5 - 3

y =2

4x - 3 = 4y + 1

Substitute y =2

4x - 3 = 4 * 2 + 1

4x - 3 = 9

Collect like terms

4x = 3 + 9

4x = 12

x =3
