You are watching: How to find the value of x and y in a parallelogram
In a parallelogram, the opposite sides are equal.
In a ABCD parallelogram, AB = CD and AD = BC.
Therefore, 5x - 2y = 4 and y = 5 - x.
Substitute y = 5 - x in the first equation: 5x - 2y = 4.
5x - 2(5-x) = 4
5x - 10 + 2x = 4
7x - 10 = 4
7x = 14
x = 2
Substitute x = 2 in the second equation: y = 5 - x.
y = 5 - 2 = 3
The values of x = 2 and y = 3.answeredOct 30, 2014by casacopExpert Please log in or register to add a comment. 0 votes
In a rectangle, the opposite sides are equal.
In a ABCD rectangle, AB = CD and AD = BC.
Therefore, 2x = 3y+5 and x = 2y+2.
Substitute x = 2y+2 in the equation 1: 2x = 3y+5.
2(2y+2) = 3y+5
4y+4 = 3y+5
y+4 = 5
y = 1
Substitute y = 1 in the equation 2: x = 2y+2.
