nevermind i got it
OpenStudy (kweenlexis):
\[11z-9-10z+7=10\]
OpenStudy (google):
you do the inverse operation for everything on that
OpenStudy (google):
so basically what you are doing here is you are doing the inverse operation for the number that isnt with the variable, for the first step put v + 9 aside and do +16 instead of -16.
do +16 on both sides
then put the answer under the equation answer
2̲0̲ ̲ =̲ ̲v̲ ̲+̲ ̲9̲ ̲-̲ ̲1̲6̲
+̲1̲̲̲6̲̲̲ ̲̲̲ ̲̲̲ ̲̲̲ ̲̲̲+̲1̲̲̲6̲̲̲
3̲6̲ ̲=̲ ̲v̲ ̲+̲ ̲9̲ ̲
-̲9̲ ̲ ̲ ̲ ̲ ̲-̲9̲
27 = V
OpenStudy (google):
that is how you solve a 2 step equation
