The step where the error occurred is Step 4. After step 3, 34x should've been added to both sides of the equation. Instead of -17x, Step 4 should say 17x, because -17+34=17. Somehow, the whole number in Step 4 also changes from 40 to 14. Nothing changed it, it should still be 40. Step 4 should be: 17x=40.
To continue solving, divide both sides by 17.
x should be 40/17 or 2 6/17.
I hope this helps :)

Is the answer to your question
Factor because if we have
yz=0 then we can assume y and/or z=0
so factor
so the easiest way is to find what 2 numbers add to -6 and multiply to get 9 so
we know that they must be both - because we must have x+x=(-) and x^2=+ so therefor they must be negative
factors of 9=3 and 3 so
-3 and -3
-3+-3=-6 perfect
(z-3)(z-3)=0
set each to zero
z-3=0
add 3
z=3
z=3 is the answer
