Answer:
x=-10
Step-by-step explanation:
We can solve this equation by first distributing the "2" to the variables inside of the parentheses:
2(x+3)=x-4
2(x)+2(3)=x-4
Simplify
2x+6=x-4
Move like terms to one side. Be careful while moving terms because if you move a term from one side to another, it's sign flips (Ex: "+" becomes "-")
2x-x=-6-4
x=-10
