i dont understand. halp. 7x time 7 = 6x

Seven times a number and seven is equal to six times a number.

- Word problems can be tricky no matter what level of math or science you are in.
- First look at the question for words that indicate mathematical symbols.
- "times" indicates multiplication
- "and" indicates addition
- "a number" means we have a variable, x, to solve for
- Now we can go from left to right and write it in a mathematical equation

- Then, solve for x

7 = 6x - 7x

7 = -1x

7/-1 = x

x = -7

- Finally, we check our work.

7(-7) + 7 = 6(-7)

-49 + 7 = -42

-42 = -42 √

**The answer is x = -7**
