No solution
3 = -2
How can 8x + 3 = 8x - 2 ??????
3 + 8x = 8x - 2
-8x + 8x = -3 - 2
0 = -5
this equation has no solution.
bcos
3 != -2
If you take all the x's to the LHS you get 8x - 8x which eliminates x entirely.
This then ceases to be an equation in x
3 + 8x = 8x -2
-3 + 8x= 8x -3
____________
8x = 8x -5
-8x=-8x-5
____________
0=5
not true, so no solution
no solutions, it's irrelevant
it dusnt make sense i dont think
u have got a typo
because if you take 8x from both sides ur left with
3=-2
you are effectively saying that 3=-2 which it cant. Above you are effectively trying to divide by zero which doesnt have an actual fixed value so you cant solve this equation!!!
