6x-16 = 4x add 16 to both sides and subtract 44 from both sides

+16= 4x+16

6x = 4x+16

-4x -4x

2x = 16

x=8

6x-16 = 4x add 16 to both sides and subtract 44 from both sides

+16= 4x+16

6x = 4x+16

-4x -4x

2x = 16

x=8

So we want to solve for x, and we do that by getting all the x terms on one side of the equal sign and all the constants on the other side. ***anything you do to one side of the equation must be done to the other side so you don't change the value of the equation***

**6x-16 = 4x **

the fastest way to separate variables and constants in this case is to subtract 6x from each side of the equation which gives us

**-16 = -2x **

Now that we have all of our x terms combined on the one side, we must divide both sides by the coefficient of the x term (-2)

**-16/-2 = -2x/-2 *** a negative times a negative or divided by a negative becomes positive!

**8 = x**

Your goal is to get x alone.

First, you want to put the x variable on one side of the equal sign.

6x-16=4x (subtract 6x from both sides)

-6x -6x

-16=-2x (now you have to divide by -2, since there is a 2 in front of the x, which means it is multiplied by it)

÷-2 ÷-2

8=x (two negative numbers gives you a positive when dividing)

6x-16=4x

Collection of like terms

6x-4x(crossing of +4x to the other side makes the sign to change to -4x)

6x-4x=16(crossing of -16 to +16)

2x=16

X=16/2

X=8
