Answer:
x = 91
Explanation:
Look at what is done to the variable:
- it is divided by 7
- the quotient has 2 subtracted
You want to undo these operations in the reverse order.
Start by adding 2, to undo the subtraction.
x/7 -2 +2 = 11 +2
x/7 = 13 . . . . . . . . . . . simplify
Now, you undo the division by 7. Multiply by 7.
7(x/7) = 7(13)
x = 91 . . . . . . simplify
