Question

Solve for x: (x + 20)/2 =3x

Answer 1

inverse operations. start by multiplying 2 on both sides to get rid of the division in the left hand part. then you would get x by itself using more inverse operations

Answer 2

x=4

Answer 3

multiply both sides by 2 . to get rid of the fraction, then subtract the x and you get 20=5x . divide by 5 and x equals 4.

Answer 4

(x+20)/2 = 3x
Multiply both sides by '2'
x+20=6x
Subtract 6x from both sides, and subtract 20 from both sides
-5x=-20
Divide both sides by -5
x = 4
