2x+1=4 then x=3/2
transpose 1 sooo ..... 2x= 4-1 , then 2x=3 ... and divide both side from to 2 to remove the to from x. so 2x/2 = 3/2 ..  answer is ... x = 3/2  then x = 3/2

2x + 1 = 4

2x + 1 -1 = 4 -1          ––> Addition property of equality, we added -1 to both sides

2x = 3

2x = 3              ––> Multiplication property of equality, we multiplied 1/2 to both sides
2     2

x = 3/2
