and 
Step-by-step explanation:
Given the above set of expressions
Find A and B
Recall her step 2

From laws of indices;

So, the expression becomes

Also, from laws of indices;

So, the expression becomes


Given that 
This implies that 
Recall that 
Divide both sides by 3



Given that 
This implies that 
So first you multiply 22 to both sides, which cancels 22 from the left side.
This will leave you with x - 3 = -22
Then you add three to both sides, which cancels -3 from the left side.
This will leave you with x = -22 + 3, also simplified to x = -19
