Tip : It may be confusing for some to take any variable other than 'x'. So if any other variable comes , substitute it with 'x' and when you write you answer just change the variable.
Answer :
-7
Step by step explanation :
Cross multiply ;
2 (a-8/3) = 2a - 16
3 (a-3/2) = 3a - 9
(We haven't cross multiplied with the denominators)
2a - 16 = 3a - 9
Now bring the terms with variables to the LHS
= 2a - 3a = -9 + 16
= -a = 7
a = -7
Since there is a negative sign for the variable we will bring the same sign to the final answer.
I hope this answer helped :)
