to keep x, u have to add 50 to each side. -50 cancels out with the positive 50 (+50). then, on the other side, -49+50= 1. therefore, x=1

Always get the x to be on a side by itself. On this problem, move the 50 to the other side of the equation by doing the inverse to each side
-49 (+50)= X-50 (+50)
which cancels out the 50 on the right side. That leaves you with 1=X

1 is the answer
how? subtract. If it's hard to visualize, remember that if you reverse the order of the subtraction, you will get the negative of the answer. It's the same as multiplying both sides by -1
-1*(-49) = -1*(x-50)
49 = -1 + 50 = 50 - 1

First you get X alone by adding 50 to both sides of the eqution because positive 50 and negative 50 added together equals zero
(-49)+50=x-50+50
1=x+0
1=x

first you bring the 50 to the other side
-49 + 50 = x
then you work it out
-49 + 50 = 1
therefore x must equal 1

It's an equation... You can do the same thing to each side at the same time...
Add 50 to each side:
50-49=x-50+50
1=x
To check, substitute 1 for x in the original equation and see if both sides equal each other... They will when the value for x is correct.

-49=x-50
+50 +50 (Adding Like Terms)
50-49=x+0 (Commutative Property of Addition, Adding Like Terms)
1=x (Adding Like Terms, Additive Identity)
x=1
The idea is to get the unknown value all by itself. Since we read from left to right, it is just common form to have x=1 instead of 1=x.
