assuming ya mean 6x-5=7-9x
remmember, you can do anything to an equation as long as you do it to both sides
6x-5=7-9x
add 9x to both sides
6x+9x-5=7+9x-9x
15x-5=7+0
15x-5=7
add 5 to both sies
15x+5-5=7+5
15x+0=12
15x=12
divide both sides by 15
[tex]x=\frac{12}{15}[/tex]
[tex]x=\frac{4}{5}[/tex]
so [tex]x=\frac{4}{5}[/tex]
