Question

8. Which equation has no solution?

Answer 1

Answer:

Step-by-step explanation:

-5+8x-9=3(x+3)

8x-14=3x+9

8x-3x-14=9

5x-14=9

5x=9+14

5x=23

x=23/5

----------------------

-216-3x=-12+6x

-216-3x-6x=-12

-216-9x=-12

9x=-216-(-12)

9x=-216+12

9x=-204

x=-204/9

x=-68/3

------------------

6-213-2x=-413-x

-207-2x=-413-x

-207-2x-(-x)=-413

-207-2x+x=-413

-207-x=-413

x=-207-(-413)

x=-207+413

x=206

------------------------

-(4x+9)=2x-3(2x+3)

-4x-9=2x-6x-9

-4x-9=-4x-9

Infinitely many solutions.
