Question

Solve using the substitution method. Show your work. If the system has no solution or an infinite number of solutions, state this.
4a + 20b = 8
8a = -40b + 16

Answer 1

This system has no solution: as ... ...
the two equations are identical ...
4a + 20b = 8 (1)
8a = -40b + 16 (2)
divide (2) by 2 and rearange ... u get
4a+20b =8 which ='s (1)

Answer 2

4a = 8 - 20b
8a = 16 - 40b
+
-----------------
12a = 24 - 60b
.... ...

Answer 3

12a + 60b = 24 :D

Answer 4

and yea this equation systems solution is not foundable, 4a = 8 - 20b = 8a = 16 - 40b so we can't find the result :D there should be a differend eqution to find the result :D

Answer 5

there is no solution for this system of equation because the never have an intersection poin as they represt 2 parallel lines.
