The perimeter of the quadrilateral is 181 cm if the length of the first side is reduced by 4 times

The perimeter of the quadrilateral is 181 cm if the length of the first side is reduced by 4 times the length of the second is reduced by 29 and the length of the third is halved, then the lengths of these sides will be equal to the length of 4 sides, find the lengths of the sides of the quadrilateral.

Perimeter – 181 cm.
Let the length of the 4 side be equal to X, then 1 side is 4X, 2 side is x + 29, and 3 side is 2x.
Let’s make the equation:
4x + x + x + 29 + 2x = 181
8x + 29 = 181
8x = 181-29
8x = 152
x = 152/8
x = 19
Verification:
4 * 19 + 19 + 19 + 29 + 2 * 19 = 181
76 + 19 + 19 + 29 + 38 = 181
181 = 181
4 side 19 cm, then 3 side 2x = 2 * 19 = 38 cm, then 2 side x + 29 = 19 + 29 = 48 cm, and 1 side 4x = 4 * 19 = 76 cm.
