Use the method of substitution to solve the linear equation!

Question

6a=6-b
6a=5-b
please help I don't get it it needs to be an ordered pair.

Answer 1

Look at the two equations. If 6a=6-b, substitute that into the other equation:

(6-b) = 5-b
add b to both sides and you have
6=5

There are no solutions to that "equation".
