First, subtract 3x from both sides. The 3x cancels out from the left side and subtracts from 5x, making it 2x.
14 = 2x.
Divide both sides by 2. Two two cancels out on the right side and becomes x. 14 divided by 2 equals 7.
The solution to this problem is 7.

3x + 14 = 5x
re-write like this
+14 = 5x - 3x
+14 = 5 - 3 times x
+14 = 2 times x
+ 14 = 2x
x = 7

3x+14=5x
or 14=5x-3x=2x
so x=14/2=7

3x + 14 = 5x
first move all the x's to the same side of the equation.
3x + 14 = 5x
-3x -3x
remember, what you do to one side, you have to do to the other side of the equation.
so now it's
14 = 2x
so to simplify, divide both sides by two.
14 = 2x
14/ 2 = 2x/ 2
7 = x
so x = 7
hope that clears things up :]

Remember that 3x is the same thing as x + x + x, and 5x is the same thing as x + x + x + x + x
That makes your equation:
x + x + x + 14 = x + x + x + x + x
That should be easier to solve. You can move the 3 'x's over to the other side, making it
14 = x + x + x + x + x - x - x - x
or
14 = x + x
which simplifies to
14 = 2x
from that point, you simply divide by 2
7 = x

Move x's to one side by subtracting 3x from 5x and then divide 14 by 2 and you get 7....

First, combine like terms. In this case, subtract 3x from both sides
1. 14= 5x -3x
Now combine the like terms.
14=2x
Solve the equation by dividing both sides by 2.
x=7

3x + 14 = 5x Subtract 3x from each side.
-3x -3x
__________
14 = 2x
Divide 14 by 2 and 2x by 2. x = 7

Combine like terms which means the 3x and 5x
1) 3x+14=5x
2) 3x-5x= -14
3) -2x= -14
4) x= -2 / -14
answer x= 7
