So you first do -4+20=16 then you subtract 16,from 55 and get it out of your equation what you have left is 3x=39 then you simplify that by dividing both sides by 3 and your answer is 13

Answer:

x = 13

Explanation:

3х – 4 + 20 = 55

3x (-4 + 20) = 55

3x + 16 = 55

Subtract 16 from both sides

3x = 39

Divide by 3 on both sides

x = 13

Hope this helps :)
