How many texting citations and how many speeding tickets were issued?

Question

During one calendar year, a state trooper issued a total of 425 citations for either texting while driving or speeding. Of these, there were 167 more speeding tickets than texting citations. How many texting citations and how many speeding tickets were issued?

Answer 1

425 = s + [s - 167] ----> 592 = 2s ----> s = 296 speeding tickets; 296 - 167 = 129 texting tickets. 

Answer 2

Speeding is texting + 167

So speeding +texting=425

Substitute texting +167 for speeding>>>

Texting +167+Texting =425

2×Texting+167=425. -167 from each

2×Texting =258.  Divide by 2

Texting. = 129

So there were 129 texting tickets and 

129+167=296 speeding tickets
