Translate into an equation: Twenty-six more than the product of a number and
17 is -42.

C) 17n + 26 = -42

“the product of a number and 17” = 17n

“twenty six more than” = + 26

And if the next question has you solve it:
17n + 26 = -42
Subtract 26 from both sides
17n = -68
Divide both sides by 17
n = -4

The answer is 1 because you have to flip the sign when dividing by negative number and 3

The answer should be 5.
