Rainbow [258]3 years ago
5 0

Step-by-step explanation

  1. First subtract the 5 from both sides so you end up with I2x+1I =7
  2. Then take the absolute value of I2x+1I and u end up with 2x+1

currently u should end up with 2x+1=7

3. now subtract one from both sides and you get 2x=6, then divide both sides by 2 and you get x=3

and if u substitute 3 for x back in the original you get 12
