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!
Answer with explanation:
It is given that
⇒ (x+40)°=(3x)°
Subtracting ,x from both sides
⇒3 x° -x° =40°
⇒ 2 x°=40°
Dividing by, 2 on both sides
x=20°
Option A:→20°
