Answer:

the answer for that expression is 7

Step-by-step explanation:

Group like terms

thus 3x - x =8+6

When a positive number Crosses the equal sign it becomes negative and Vice versa .

furthermore

2x =14

dividing through by 2

2x/2 =14/2

x= 7 as final answer.

Answer:

x=3.5

Step-by-step explanation:

3x-6=x+8

The first thing you need to do is move x to one side so you can solve for it. The easiest way to do this is by subtracting x from both sides, to move it to the left side of the equation.

3x-6=x+8

-x       -x

3x-6-x=8

Next, combine like terms.

4x-6=8

Now we need to work on getting x alone. The only number on the left side of the equation is -6, so we add 6 to both sides to move it to the right side.

4x-6=8

+6      +6

4x=14

Finally, we need to get rid of that 4 by dividing by 4 on both sides.

4x=14

/4    /4

x=3.5
