SOLUTION

TO CHOOSE THE CORRECT OPTION

Which of the following is the value of x such that

5x – 12 = - 2

(a) 2

(b) - 2

(c) 23

(d) 10

EVALUATION

Here the given equation is

5x – 12 = - 2

We find the value of x as below

$\displaystyle \sf{ 5x - 12 = - 2}$

$\displaystyle \sf{ \implies 5x = 12 - 2}$

$\displaystyle \sf{ \implies 5x = 10}$

$\displaystyle \sf{ \implies x = \frac{10}{5} }$

$\displaystyle \sf{ \implies x = 2 }$

FINAL ANSWER

Hence the correct option is (a) 2

Answer 2

Answer:

=> The value of the expression 12.

Step-by-step explanation:

Given that:-

$5x -12 = -2$

To find:- The value of the x for $5x -12 = -2$,

By using the DMAS concept,

As we have,

=> $5x -12 = -2$

Add both sides by $12$, we get

=> $5x-12+12=-2+12$

Simplifying it further, we get

=> $5x=10$

Now, divide both sides by $5$:

=> $x=2$

Hence, the required solution is 2.
