the answer would be 3 because you need to do the opposite of addition for the 3 so you would subtract the 3 from both sides of the equal sign then you woul dbe left with 2x=3 then you would do the opposite of multiplication which is divison so you would divide by 2 on each side of the equals sign to get an answer or 3

isolate X by subtracting 3 from both sides
2X+3(-3)=9(-3)
2X=6
divide both sides by 2
2x/2=X; 6/2=3
X=3

2x + 3 = 9
2x + 3 - 3 = 9 - 3
2x = 6
2x/2 = 6/2
x = 3
The answer is x = 3
Insert the x value into the equation
- - - - - - - - - - - - - - - - - - - - - - -
2x + 3 = 9
2(3) + 3 = 9
6 + 3 = 9
9 = 9
- - - - - - - -
The solution set is { 3 }
- - - - - -s-
