Hello!
We are given the equation below.
x+40=3x
We want to get all of the variables on side. First of all let's subtract 40 from both sides.
x=3x-40
Now we rearrange our equation so the commutative property will work.
x=3x+(-40)
x=-40+3x
Now we subtract 3x from both sides.
-2x=-40
We divide both sides by -2.
x=20
Our answer is A) 20.
I hope this helps!
(2x+1)+89=180. 180 is the angle of a straight line. Set your two known sides equal to 180 and solve for x if needed.

Since there is no diagram to support the question, we'll assume that:

This gives:

Subtract 22 from both sides
