Question

solve the eqation with checking​

Answer 1

Step-by-step explanation:

9z -13 =11z +27

→9z -11 z = 27+13

→-2z = 40

→z =(40/(-2)= -20

We have ,

LHS = 9(-20)-13= -193

RHS =11(-20)+27= -220+27=-193

→LHS=RHS

Answer 2

9z-13=11z+27

9z-11z = 13+27

- 2z = 40

z= 40/-2

z= -20

hope it helps
