Answer
105
Step-by-step explanation:
first bring 3 to the second power and get 9
then you have 7+8(9-2)
then add 7+8 and get 15
then you have 15(9-2)
then subtract 9-2 and get 7 
then you have 15(7)
then times them and get 105
 
        
             
        
        
        
Multiple 5x70 to get 350. Which makes the equation 350=5x and then you have to divide both sides by 5 to get x by itself.  so 5x/5 and 350/5 makes x=70
