Question 595088
{{{-17v-9=8}}} Start with the given equation.



{{{-17v=8+9}}} Add {{{9}}} to both sides.



{{{-17v=17}}} Combine like terms on the right side.



{{{v=(17)/(-17)}}} Divide both sides by {{{-17}}} to isolate {{{v}}}.



{{{v=-1}}} Reduce.

-------------------------------------------------------


{{{2v-5}}} Now go back to the original expression



{{{2(-1)-5}}} Plug in {{{v=-1}}}



{{{-2-5}}} Multiply 



{{{-7}}} Subtract



So {{{2v-5=-7}}} when {{{-17v-9=8}}}
