Answer: [tex]x=-\frac{7}{4}[/tex]
Step-by-step explanation:
Given the following equation provided in the exercise:
[tex]x+7=-3x[/tex]
You can follow these steps in order to solve for the variable "x" and find its value:
1. You must subtract 7 tp both sides of the equation. Then:
[tex]x+7-(7)=-3x-(7)\\\\x=-3x-7[/tex]
2. Now you need to add [tex]3x[/tex] to both sides
[tex]x+(3x)=-3x-7+(3x)\\\\4x=-7[/tex]
3. Finally, you must divide both sides of the equation by 4. Therefore, you get the following solution:
[tex]\frac{4x}{4}=\frac{-7}{4}\\\\x=-\frac{7}{4}[/tex]
