We must solve the following equation:
[tex]-6=\frac{x}{4}-1[/tex]1) We sum to both sides +1, then we simplify:
[tex]\begin{gathered} -6+1=\frac{x}{4}-1+1 \\ -5=\frac{x}{4} \end{gathered}[/tex]2) We multiply both sides by 4, then we simplify:
[tex]\begin{gathered} 4\cdot(-5)=4\cdot\frac{x}{4} \\ -20=x \end{gathered}[/tex]Answer
[tex]x=-20[/tex]
