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
That isn't the final answer, though. To find Conner's speed use
#39+19 = 58#
