Answer:
equation: x-42=50
answer: x=8
Explanation:
lets write the equation. We have 42 less than x is -50. 42 less than x could translate to x-42 and if it is 50, then that is what x-42 equals.
So we would have x-42=50
Now you can carry over the -42 to start solving
x-42=50
+42 +42
(notice it is added on both sides. I add them to get rid of the -42 on the x side and whatever you do to one side you ALWAYS do to the other.)
x= 50-42
x= 8
i hope this helps :)
