Question

the diffrence of a number times 9 and 4 equals 8

Answer 1

you would right it out like this.
\[9x-4=8\]\[9x-4\color{red} {~~~+4}=8\color{red} {~~~+4}\]\[9x=12\]\[9x~~~\color{red} {\div 9}=12~~~\color{red} {\div 9}\]\[x=\frac{12}{9}\]\[x=\frac{12\color{red} {~~\div 3}}{9\color{red} {~~\div 3}}\]\[x=\frac{4}{3}~~~~~~~~~or~~~~~~~~~x=1\frac{1}{3}\]

Hope this helps you understand the problem.
