Answer 2

Given :

An equation $3x+17=-12$

To find :

The value of $x$.

Step-by-step explanation:

• The given equation is

        $3x+17=-12$

• Take the number to the other side of the equation

        $3x=-12-17$

• Sum it all up

        $3x=-29$

• Take the number to the other side

        $x=\frac{-29}{3}$

• Divide the values

• Then the value of $x$ would be    

        $x=-9.6$

• For checking, substitute the value of $x$ in the equation.
• If the value becomes nearly or actually equal, then the value of $x$ is actually equal.

• Substitute the value in the equation

        $3(-9.6)+17=-12$

• Remove the brackets

• Multiply the values

       $-28.8+17=-12$

• Let's take $28.8$ as $29$. If the number after decimal is greater than or equal to 5.
• Then, the equation would be

       $-29+17=-12$

• Sum it all up
• Then the LHS will become $-12$
• Just as the RHS.
• Which means the value of $x$ is $-28.8$

Final answer :

The value of x is $-28.8$.
