20 - (8+x) - ( x-1) =39
Answered by reb
-13. Solve for
x
by simplifying both sides of the equation, then isolating the variable.
Answered by Ms. Sue
There is no variable.
x - x = 0
Answered by reb
I'm sorry that was probably confusing x= -13. A way to check would to be replacing x with -13 and solving the equation so 20-(8+ -13)-(-13-1)= 39

20 - (8+x) - ( x-1) = 39
20 - 8 - x - x + 1 = 39
13-2x = 39
and you can see that x = -13
