Take note of the order of operation. You need to solve in this order

1)Do operations in parentheses.
2) Multiply and divide from left to right.
3) Add and subtract from left to right.

To simplify further, find the common Mulitple of the remaining values. If you have Prime Number( i.e 7, 11) , you do not need to simplify
