Question

Trey can type 19 words per minute faster than Conner. Their combined typing speed is 97 words per minute. How fast does Conner type?

Answer 1

`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`
