58

Explanation:

We can use this equation to solve it:

x + (19 +x) = 97

  • x is Conner's speed, which is unknown

  • 19+x is Trey's speed, which is 19 words per minute faster than Conner

  • 97 is their total combined speed

Now we simplify the equation

2x + 19 = 97" " (Combine like terms)

2x +19 - 19 = 97 -19" " (isolate x by subtracting 19 from both sides)

2x = 78

x/2 = 78/2" " (divide both sides by 2 to isolate x)

x=39

So Trey's speed is 39

That isn't the final answer, though. To find Conner's speed use x+19

39+19 = 58
