Hi Jenaya,
Let's use the variable, x , to represent the unknown number.
The text, "four times the difference of a number and 3" would be written as: 4(x - 3)
The text, "7 times the sum of the number and 4" would be written as: 7(x + 4)
The text, " is the same as" would be written as an equal sign: =
Now we can write the following equation to show this situation:
4(x - 3) = 7(x + 4)
