Subtract 4x from both sides:
-x-3=-10
Add 3 from both sides:
-x=-7
Divide -1 from both sides:
x=7
Check:
3(7)-3=4(7)-10
21-3=28-10
18=18

*Solve for "x" by keeping it on one side > the right side is best:
First: subtract 4x from both sides and combine "like" terms:
3x - 3 - 4x = 4x - 4x - 10
3x - 4x - 3 = -10
-x - 3 = -10
Second: add 3 to both sides > opposite side means opposite sign:
-x - 3 + 3 = -10 + 3
-x = -7
Third: "x" can never be negative > change the signs:
x = 7

3x - 3 = 4x - 10
-3 = x - 10
x = 7

3x - 3 = 4x - 10
3x - 3 - 3x = 4x - 10 - 3x
- 3 = x - 10
- 3 + 10 = x - 10 + 10
7 = x
The answer is x = 7
Insert the x value into the equation
- - - - - - - - - - - - - - - - -- - - - - - -
3x - 3 = 4x - 10
3(7) - 3 = 4(7) - 10
21 - 3 = 28 - 10
18 = 18

3x-3=4x-10
Isolate the x value by subtracting 3x from both sides of the =
-3x+3x-3=4x-3x-10
Simplify
-3=x-10
Add 10 to both sides of the = to figure for x
-3+10=x-10+10
Simplify
7=x
Now prove your work by using 7 for the x value
3(7)-3=4(7)-10
21-3=28-10
18=18
Now you are certian this is the correct answer

3x-3=4x-10 [add 10 to both sides]
3x+7=4x [subtract 3x from both sides]
x=7

Get all the x terms on one side, then solve:
3x-3=4x-10
3x - 3 = 4x - 10
3x - 4x = -10 + 3
-x = -7
x = 7
To verify the answer, substitute it back into the equation:
3(7)-3 = 4(7)-10
18 = 18
