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](https://img.qammunity.org/2022/formulas/mathematics/high-school/nmzzqarjuq5sfshgsjckww3jvhcj00h1i0.png)
First, we must apply the distributive property.
![\sf -20-2x=4](https://img.qammunity.org/2022/formulas/mathematics/high-school/r60d3fpmwyy1v2smax9426qlbo51vokjdo.png)
Now we move the independent term to the second degree.
![\sf -2x=4+20](https://img.qammunity.org/2022/formulas/mathematics/high-school/1nor77ujjzo9hh7ld3chsvf9suu3lvte7b.png)
We add similar terms.
![\sf -2x=24](https://img.qammunity.org/2022/formulas/mathematics/high-school/5lle3d2a6j3lf70u0aj6ugn451rcg0yuys.png)
We isolated the term "x".
![\sf x=(24)/(-2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/4ibqxkxp46q0wwz30gg8p1unjpr3n7kzru.png)
Finally, we carry out the division. Discovering, in this way, the solution.
