The like terms are:
12x and 8x - they have the same variables
8, 55, 3, and 180 - they are all regular numbers (if you know what I mean)
Answer:
P = 80 degrees and R = 45 degrees
Step-by-step explanation:
first simplify: 20x + 60 = 180
20x = 120
x = 6
next plug in 6 for each equation: 12(6) + 8 = 80
8(6) - 3 = 45
finally check to see if the answer is correct: 55 + 45 + 80 = 180
