Solve. –9x + 6 + 7x = –2x – 7?

Answer 1

- 9x + 6 + 7x = - 2x - 7

- 2x + 6 = - 2x - 7

- 2x + 6 + 2x = - 2x - 7 + 2x

The coefficienta and variables cancell. No solution

- - - - - - - -s-

Answer 2

–9x + 6 + 7x = –2x – 7
0 = 0
no solutions possible

Answer 3

Remember that what happens to one side of the equation must happen to the other to maintain balance.

-9x + 6 + 7x = -2x - 7: first simplify

6 - 2x = -2x - 7

13 - 2x = -2x

I believe that you have copied this incorrectly. The final result would be that 13 = 0 and that is not a valid answer.

Answer 4

-9x + 6 + 7 x = -2x - 7
-2x + 6 = -2x -7 (group like terms)
add 2x to both sides
6 = -7

clearly this is not possible. It must be a typo in our problem. Even if x was 0 it would still not work

Answer 5

-9x+6+7x=-2x-7

move all variables to the left and constants to the right.
-9x+7x+2x=-7+6

add all the variables.
0x = 1?

OMG!!!... there's no answer...
final answer: undefined; 1/0 is undefined... try it with a calculator and it will show a math error...

Answer 6

plzzzzzzzzzzzzzzzzzzzzzzzzzzz, choose me as ur best answer,ok the answer is x= - 13, cos look

u should put the numberswith x's together and only numbers together, and whenn uchange the number to the other side thesign becomes the opposite, so that is how it would look like

-9x+7x+2x= - 6 - 7
-9x+9x= - 13
(-9x + 9x)= -13
x =-13
choose as best answer, if its right

Answer 7

This equation has no solutions. It reduces to 6=7, which is meaningless, unless of course x tends to infinity.

Answer 8

Undefined answer.

Answer 9

explicit equation!!!
no answers possible!!!

Answer 10

x gets cancelled result is no answer.........
