Triangles add to 180 so you can do 42+60= 102 now add that to 14 which is 116 so your new equation is (8x+116)=180 so now 180-116= 64 and 8/64 = 8
ANSWER x=8
P + s = 200......p = 200 - s
20p + 15s = 3400
20(200 - s) + 15s = 3400
4000 - 20s + 15s = 3400
-20s + 15s = 3400 - 4000
-5s = - 600
s = -600/-5
s = 120 <=== there were 120 standard tickets sold
p + s = 200
p + 120 = 200
p = 200 - 120
p = 80 <=== there were 80 premium tickets sold
