Answer:
   x = 3 1/2
Step-by-step explanation:
You could simplify the given equation first, then solve the resulting 2-step linear equation. It might work better to undo the operations done to the variable.
<h3>Solution</h3>
   (5 1/6 -x)(2.7) -5 3/4 = -1 1/4 . . . . . given
   (5 1/6) -x)(2.7) = 4 1/2 . . . . . . . add 5 3/4 to both sides
   (5 1/6 -x) = 4.5/2.7 = 5/3 . . . divide by 2.7
   31/6 -10/6 = x . . . . . . . . . . add x-5/3, use common denominators
   21/6 = x = 7/2
   x = 3 1/2
 
        
             
        
        
        
It's hard to read your picture
But if your equation is
(-3)^2 + (-2)^3
then its:
-3*-3 + -2*-2*-2 = -9 - 8 = -17
