Answer 2

Answer:

=> The value of x is -27.

Step-by-step explanation:

Given that:-

$3x - 12 = 4x + 15$

To find:- The value of the expression,

Solving this by using the DMAS rule.  

DMAS:- Division ( ÷ )    

            Multiplication ( × )  

            Addition ( + )      

            Subtraction ( - )  

Now, add $12$ on both the sides of the equation:

=> $3x - 12 +12= 4x + 15+12$

=> $3x=4x+27$

Subtract $4x$ on both sides,

=> $3x-4x=4x+27-4x$

=> $-x=27$

Now, divide both the sides by $-1$, we get

=> $x=27$

Hence, the required solution is 27.
