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 is19 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" " (isolatex by subtracting19 from both sides)
2x = 78
x/2 = 78/2" " (divide both sides by2 to isolatex )
x=39
So Trey's speed is
That isn't the final answer, though. To find Conner's speed use
39+19 = 58
