Answer 1

$\Huge\tt\orange{answer~~~↓}$

$\sf{ }$

$\large\bf{{\underline{To~solve}}:}$

$\tt{~~~~~~~~~~~ 7x+2=-19}$

$\tt{:\implies 7x=-19-2}$

$\tt{:\implies 7x=-21}$

$\tt{:\implies x={\dfrac{-21}{7}}}$

$\tt{:\implies x={\orange{\underline{\boxed{\bf -3}}}}}$

Answer 2

Answer:

The value of x$=-3$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question 7x + 2 = -19​

We have find the value of x in the above question.

Here we will use the transposition method.  

Hence, for solving the above equation, we will solve it by separating the like terms at one side.

So, we will shift 2 from LHS to RHS the sign will change from positive to negative,

As we get,

$7x+2=-19\\7x=-19-2\\7x=-21$

Dividing both side by 7 we get ,

$\frac{7x}{7} =\frac{-21}{7}$

Simplifying further we get,

$x=-3$

Hence the value of x$=-3$
