Question

7t=80+9t solve for t Show work please

Answer 1

Equation: 7t= 80+9t
Cancel out 9t and bring it to the other side: 7t-9t=80 
                                                                     -2t=80
Divided -2 from t to isolate t: t= 80/-2
                                              t= -40

Answer 2

7t=80+9t Subtract 9t by 7t with will be -2t, then divide -2t by -2 and divide 80 by -2 and should get -40
