Solve this algebra please.. 6x - 7 - 7x = - 16?

6x - 7 - 7x = - 16.

First combine the x terms. 6x - 7x = - x. So you now have:

-x - 7 = - 16. Now add 7 to both sides of the equation.

- x - 7 + 7 = - 16 + 7. The - 7 and + 7 on the left side cancel each other out. You now have.

- x = - 9. Multiply both sides by - 1 to get:

x = 9. Answer

6x - 7 - 7x = -16
6x - 7x = 7 - 16
(6-7)x = -9
-1x = -9
x = 9

Just combine terms that are the same and then simplify.

6x - 7x = -16 + 7

-x = -9

x = -9/-1

x = 9

PROVE:

Let x = 9

6(9) - 7 - 7(9) = -16

54 - 7 - 63 = -16

47 - 63 = -16

-16 = -16...It checks!!

So, x = 9 is right.

6x - 7 - 7x = -16
6x - 7x = 7 - 16
-x = -9
x = -9/(-1)
x = 9

6x - 7 - 7x = - 16
6x - 7x = -16 + 7
-x = - 9
x = 9

6x - 7 - 7x = -16
6x - 7x = 7 - 16
-x = -9
x = 9

6x - 7 - 7x = - 16
- x = - 9
x = 9.

Hint: combine like terms and remember that when you cross from one side of the equal sign to the other side, change signs.

16 - 7 = 7x - 6x
9 = x

6x-7-7x=-16--->>>data
6x-7x=-16+7--->>>collect the like terms together,i.e,while you shift a term from LHS to RHS or vice verse you should change it's sign(for addition subtraction)and cross multiply(for multiplication division)
so you get -x=-9
therefore x=9(-ve sign on both sides get cancelled)

hope this helps =)

Combine like terms on the left:
6x-7x= -x

We have:
-x-7= -16

Add 7 to both sides:
-x= -9

Multiply both sides by -1:
x=9 (answer)

Check:
6(9)-7-7(9)= -16
54-7-63= -16
-16= -16

This is a true statement, so I know that x is in fact 9.
