You are on right track
 
2(x-3) + 1 = 3x -4
 
2x - 6 +1 = 3x - 4
2x -5 = 3x -4
subtract 2x from both sides
 
2x - 2x -5 = 3x - 2x -4
-5 = x -4
add + 5 on both sides
 
- 5 + 5 = x -4 + 5
0 = x + 1
 
add -1 on both sides
 
-1 = x +1 -1
-1 = x

Hi Lashae;
2(x-3)+1=3x=4
I assume this is...
2(x-3)+1=3x+4
IF I AM MISTAKEN, PLEASE LET ME KNOW.
Let's distribute the 2...
2x-6+1=3x+4
2x-5=3x+4
Let's subtract 2x from both sides...
-2x+2x-5=-2x+3x+4
-5=x+4
Let's subtract 4 from both sides...
-4-5=x+4-4
-9=x
Let's check our work...
2(x-3)+1=3x+4
2(-9-3)+1=[(3)(-9)]+4
2(-12)+1=(-27)+4
-24+1=-23
-23=-23

Jusyt multiply it out, combine similar terms, and solve.
 
2(x-3)+1=3x-4 (assume typo, it is minus 4, not equals 4?)
2x-6+1=3x-4
Subtract 2x from both sides ... 5=x-4 ... x=9

Hi Alex;
I assumed it is +4, not -4, because on my computer keyboard, the + and = sign are the same button.
