The equation should be
j = 30 + 3a
j + a = 210
Solving the equation
j + a = 210
(30 + 3a) + a = 210
30 + 4a = 210
4a = 180
a = 45
j = 30 + 3a
j = 30 + 3 × 45
j = 30 + 135
j = 165
Aiden's weight is 45 pounds, Jonathan's weight is 165 pounds

Answer:
x = 102
z = 21
Step-by-step explanation:
x and 78 are same side alternate exterior angles, so they are supplementary.
x + 78 = 180
x = 102
5z - 27 and x are a linear pair, so they are supplementary.
5z - 27 + x = 180
5z - 27 + 102 = 180
5z = 105
z = 21
