First off, you have to get rid of your parenthesis. You would multiple both X and -2 by -3, and you would multiply both X and 1 by 4 to get:
-3X+6+4=4X+4
-3X+10=4X+4
-7X+10=4
-7X= -6
X=6/7
Put the answer back into the original problem to see if our answer is correct.
-3X+6+4=4X+4
-3(6/7)+6+4=4(6/7)+4
-18/7+10=24/7+4
To add fractions, you need to find a common denominator. Since our two fractions already have a 7 on the bottom, we can change the whole numbers to fractions with a 7 on the bottom. To do that, we simply multiply the whole numbers by 7 to get this equation:
-18/7+70/7=24/7+28/7
52/7=52/7

Well, it's been a while, but here goes:
1. First I would multiply out the equation to get rid of the parentheses. On the left side, multiply negative 3 by x and by negative 2. On the right side, multiply 4 by x and by 1). This gives you the following:
-3x + 6 + 4 = 4x +4
2. Next I would get all the x's on one side, and the numbers without x's on the other. Add 3x to both sides; then subtract 4 from both sides. This gives you the following:
7x = 6
3. Finally, solve for x by dividing both sides by 7.
x = 6/7 or 0.8571428571...

-3(x-2)+4 = 4(x+1)
=> -3x + 6 + 4 = 4x + 4
=>4x + 3x = 6
=>7x = 6
=> x = 6/7

Do the distributive properties first
-3x + 6 + 4 = 4x + 4
-3x + 10 = 4x + 4
10 = 7x + 4
6 = 7x
x = 6/7

Distributing the factors (-3 and 4) over the parenthesized parts:
-3x+6 + 4 = 4x+4
or: -3x + 10 = 4x + 4
Add 3x to both sides:
10 = 7x + 4
Subtract 4 from both sides:
6 = 7x
Divide both sides by 7:
6/7 = x.

1. Distribute.
-3x + 6 + 4 = 4x + 4
2. Combine on each side.
-3x + 10 = 4x + 4
3. Get variable to one side.
10 = 7x + 4
4. Isolate term with variable.
6 = 7x
5. Divide both sides by the coefficient.
6/7 = x
