5x - 6 = 4x + 8
5x - 4x - 6 + 6 = 4x - 4x + 8 + 6
x = 14

can you explain how you got the two sixes and how you got all of that to get the answer
math - Ms. Sue, Friday, March 5, 2010 at 4:30pm
I added 6 to both sides of the equation.
The 6's on the left side of the equation cancel each other out. That leaves x = 8 + 6

im sorry i know you might think im stupid but i just need help on this but why six
math - Ms. Sue, Friday, March 5, 2010 at 6:23pm
The object is to get the unknowns on one side of the equation and the knowns on the other side.
On the left side, the original equation is: 5x - 6
We need to add 6 to both sides in order to move it to the right side.
