  • Response:

The solution to this equation is: x = -12

  • What is the first degree equation?

First degree equation is an equality between members where we find at least one variable.

  • How to solve this equation?

We have the equation:


\sf -2(10+x)=4

First, we must apply the distributive property.


\sf -20-2x=4

Now we move the independent term to the second degree.


\sf -2x=4+20

We add similar terms.


\sf -2x=24

We isolated the term "x".


\sf x=(24)/(-2)

Finally, we carry out the division. Discovering, in this way, the solution.


\boxed{\boxed{\sf x=-12}}

Answer:

x = -12

Explanation:

-2(10 + x) = 4​

Divide each side by -2

-2(10 + x) / -2 = 4/-2

(10 + x) = -2​

Subtract 10 from each side

10+x-10 = -2-10

x = -12
