Answer:
x=-5
Explanation:
Given the equation
[tex]6\mleft(x+3\mright)-(x+4)=-11[/tex]First, we open the brackets
[tex]6x+18-x-4=-11[/tex]Next, we collect like terms and simplify
[tex]\begin{gathered} 6x-x=-11+4-18 \\ 5x=-25 \end{gathered}[/tex]Finally, divide both sides by 5.
[tex]\begin{gathered} \frac{5x}{5}=-\frac{25}{5} \\ x=-5 \end{gathered}[/tex]
