2x + 4 = x + 8 combine like words. The x's and the constants. first subtract 4 from each area and we get 2x = x + 4 now subtact x from each area and we get x = 4 the answer 5x - 2 = 3x - 8 lower back combine like words with the aid of including 2 to each area and we get 5x = 3x - 6 subtract 3x from each area 2x = -6 divide with the aid of two each area of the equation and we get x = - 3 3x - 8 = 2 - 2x combine words 3x = 10 - 2x upload 2x t each area 5x = 10 divide each area with the aid of 5 and we get x = 2 x/5 = 10 multiply each area with the aid of 5 and we get x = 50 x/5 < 16 mulltiply each area with the aid of 5 and we get x < 80

3x - 4 = 2x + 8 - 5x
3x - 4 = 8 - 3x
3x + 3x = 8 + 4
6x = 12
x = 12/6
x = 2

3x-4=2x+8-5x add 3x to each side
6x-4=8 add 4 to each side
6x=12 divide by 6
x=2

3x-4=2x+8-5x
3x-4=-3x+8
3x+3x=8+4
6x=12
x=12/6
x=2
so the value of x=2

3x - 2x + 5x = 8 + 4
6x = 12
x = 2

First combine all like terms:
3x - 4 = -3x + 8
Now separate the x by subtraction and addition:
6x = 12
x = 2

First of all, group symilar items on each size, that means:
3x-4=-3x+8
Now put all items containing an x on one side (usually but not neccesarily, left), all others on the other side (when you take something from one side of the equation to the other, its sign changes):
3x+3x=8+4
So now you have
6x=12
Now you divide by the coefficient of x, which is 6:
x=2
So this is your answer: x=2
Good luck!
