PLEASE HELP I DONT UNDERSTAND!!

Answer:
see explanation
Step-by-step explanation:
3x and 144 are adjacent angles on a straight line and sum to 180°
3x + 144 = 180 ( subtract 144 from both sides )
3x = 36 ← value of 3x
divide both sides by 3
x = 12
and
2y - 5 and 95 are vertically opposite angles and are congruent, so
2y - 5 = 95 ← value of 2y - 5
add 5 to both sides
2y = 100 ( divide both sides by 2 )
y = 50
Then
x + y = 12 + 50 = 62
Answer:
3x = 36; 2y - 5 = 95; x + y = 62
Step-by-step explanation:
Supplementary angles add up to 180
180 = 3x + 144
36 = 3x
x = 12
Vertically opposite angles are equal
95 = 2y - 5
100 = 2y
y = 50
x + y = 12 + 50 = 62
