i need help @google

OpenStudy (google):

With what?

KjSaif (kjsaif):

what grade

OpenStudy (google):

you need help with a 3 or 4 step equation?

OpenStudy (kweenlexis):

8th grade and hold up @google

OpenStudy (google):

alright if you give me an equation write it correctly

KjSaif (kjsaif):

ok great i can do 8th grade

OpenStudy (kweenlexis):

\[20= v+9-16\]

OpenStudy (google):

v= 27

KjSaif (kjsaif):

any choices

KjSaif (kjsaif):

Google got it Is 27

OpenStudy (google):

remember isolate the variable and simplify on both sides

KjSaif (kjsaif):

^^

OpenStudy (kweenlexis):

i odnt get how you got tht

OpenStudy (google):

oh ok

OpenStudy (google):

so ill draw it up for you

|dw:1473779511450:dw|

OpenStudy (kweenlexis):

how you gety 27 yu got 9 right there

OpenStudy (kweenlexis):

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

OpenStudy (kweenlexis):

oohh i get t nowww thank you
