2X+4=20+5X

A) 1/2 B) - 1/2 C) 2 D) - 2

It seems that your options aren't correct as the right answer is - 5.3333 ... (recurring)

Step-by-step explanation:

1) 2x + 4 = 20 + 5x (subtract by the smallest unknown)

-2x - 2x

2) 4 = 20 + 3x

-20 - 20 (now subtract each side by 20 as we want to leave the unknown on one side and another number on the other side.

3) - 16 = 3x (Divide each side by 3)

:3 = : 3

4) - 5.33333 ... = x

Now we have found x but if you're unsure you can substitute to see if your answer is correct. 2 x - 5.3333 + 4 = - 6.666620 + 5 x - 5.3333 = - 6.6665Our answer is correct! (When answers are rounded, it is equal to the same thing).
