Answer:
Explanation:
We would evaluate the left hand side of the equation first. The left hand side of the equation contains
- (5-(a+1)) = - (5 - a - 1) = - 5 + a + 1
Next step is to evaluate the right hand side of the equation first. The right hand side of the equation contains
9-(5-(22-3)) = 9-(5-22+ 3) = 9-5+22- 3 = 23
Therefore
- 5 + a + 1 = 23
-4 + a = 23
Adding 4 to the left hand side and the right hand side of the equation, it becomes
- 4 + 4 + a = 23 + 4
a = 27
