Question

Solve the equation. Then check your solution. 11-19m=-16m-16

Answer 1

11-19m=-16m-16

move -16m to the other side

sign changes from -16m to +16m

11-19m+16m =-16m+16m-16 ( combine like terms)

11-19m+16m=-16

11-3m=-16

move 11 to the other side

sign changes from +11 to -11

11-11-3m=-16-11

-3m=-16-11

-3m=-27

divide both sides by -3 to get +m and by itself

-3m/-3=-27/-3

m=9

Check solution by using substitution method

11-19m=-16m-16

11-19(9)=-16(9)-16

11-171=-144-16

-160=-160

Answer:

m=9
