6x-7x=20
what is the value of x-
-x=20
Which means x=-20
To find the value of x in the equation 6x - 7x = 20, we can start by simplifying the equation by combining like terms.
6x - 7x can be simplified to -x.
So the equation becomes -x = 20.
To isolate x, we can multiply both sides of the equation by -1 to get x by itself.
Multiplying -1 to both sides gives us x = -20.
Therefore, the value of x in the equation 6x - 7x = 20 is -20.
