Question

5a = 6-b
5a = 4-b

Using the substitution method this linear equation ..I am saying that it has one solution? Would this be correct?

Answer 1

No solution

Answer 2

5a + b = 6
5a + b = 4

Impossible

Answer 3

Not really?
6-b = 5a = 4-b, correct?

a =(6-b)/5 and a= (4-b)/5

Answer 4

Put it this way: If you subtracted the equations, you end up with 0 = 2 which is false.

Answer 5

no solution
