Answer: 
Step-by-step explanation:
In the given picture, a parallelogram PQRS is given with angle 101°.
In a parallelogram opposite angles are equal.
Since, y is opposite to 101°.
Therefore y=101°
Also, the sum of the adjacent angles of a parallelogram is 180°

Answer:
3
Step-by-step explanation:
2×-3y = 12 ( multiply whit 4)
3x + 4y =1 (multiply whit 3 )
8x -12y =48
9X+ 12y = 3
if you add this equations
17X =51
X= 51 / 17
x=3
