Answer:
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.
