6a=3-b
6a=2-b

Answer 1

Answer 2

use the method of substitution to solve the system of linear equations

Answer 3

wrong question?

Answer 4

right away you see that the two rows are equal to different things. 6a cant be = to 3-b AND 2-b . therefore there is no solution.

otherwise the way you'd go about this is

3-b = 2-b --> 1 = 0 which is false
