Lisa solved the equation x+6=8+x and claimed that the solution is x=-1/3. Is she correct? Explain

Lisa is not right.

Step-by-step explanation:

The equation Lisa is solving is x+6=8+x

The solution for the given value will be the value of x.

To solve for x we isolate the x term that is bring both x on one side of the equal sign.

Subtracting x both sides we have:

x-x+6=8+x-x

The x on both sides gets cancel and hence there is no value of x that will satisfy the equation x+6=8+x.

So Lisa solution is not right.
