Answer:
x-2=x x=0
No Solution
x+1=1-x
Cancel
1 on both sides
Subtract
−x from both sides
x+x=0
Simplify x
+x to 2x
2x=0

413/14= 29.5
The alternative method is to list all of the tens multiples, and the smaller multiples when you're getting close to the answer, and this will be able to help you.
14x10= 140
14x20=280
14x30= 420 (which is slightly too big)
14x29= 406 (slightly too small)
14x29.5= 413
Hope this helps :)
