You can put this solution on YOUR website! To solve this word problem, we need to convert it into an equation. Let's first break down each part of the sentence:
"The product of 7 and a number" -- product means multiplication. So, 7 multiplied by some number. Let's use the letter y to represent the unknown number. Doing this, we can rewrite this as 7y
"Less than 85" -- less than means subtraction. So, we will subtract 85 from 7y. In other words, 7y - 85
"is negative 29" -- is means equals, so = -29
Put all of this together, and we have:
7y - 85 = -29
Now we can solve. First, add 85 to both sides of the equation:
85 - 85 + 7y = -29 + 85, giving us 7y = 56
Dividing both sides by 7 will give us y, which is our unknown number:
 = 
So, our final answer is 8. 8 is the unknown number.
