2 x + 3 = 9
-3 = -3
2x= 6
divide by 1/2 on both sides to get x by itself
x=3

2x + 3 = 9
2x + 3 - 3 = 9 - 3
2x + 0 = 6
2x = 6
x = 3

Subtract 2x from both sides:
2x+3 = 9x
-2x -2x
Leaving you with:
3 = 7x
Now divide the 7 on both sides:
3/7 = x

2x + 3 = 9 + x/10
20x + 30 = 90 + x
19x = 60
x = 60/19
that number is irrational, i think. not sure if that works

2x+3=9x
-2x -2x 1. Combine like terms; subtract 2x to get the x on
........... ... one side
3=7x 2. Isolate x; divide by 7
/7 /7
..........
3/7=x You are left with the answer...3/7=x

2x = 3 = 9x
-2x -2x
Subtract 2x from both sides
3 = 7x
3/7 = 7x/7
Divide 7 from both sides
3/7 = x
The answer is x = 3/7
The solution set is { 3/7 }
