The value of y in the line segment is 4

How to find the variable in a line segment ?

RT is the total line segment.

Therefore,

RS = 3y + 3

ST = 2y + 8

RT = 31

Hence,

RT = RS + ST

31 = 3y + 3 + 2y + 8

31 = 3y + 2y + 3 + 8

31 = 5y + 11

31 - 11 = 5y

20 = 5y

divide both sides by 5

20 / 5 = 5y / 5

y = 4
