Question

Find the value of xx and yy in the parallelogram below.

Answer 1

Mark the definition of parallelogram

• Opposite sides are parallel
• Opposite sides are equal

So

• 10x-7=63
• 10x=70
• x=7

And

• -5y+3=83
• -5y=80
• y=-16

Answer 2

Answer: x = 7 and y = -17

Explanation:

Opposite sides of parallelograms are equal.

-5y + 3 = 88

-5y = 85

y = -17

10x - 7 = 63

10x = 70

x = 7
