On the left side of the equation, you have like terms : 2x and 4x
That means that you can combine them
2x+4x=3x+1
6x=3x+1
Now, since the 3x is on the other side of the equation, you have to perform the opposite operation by subtracting 3x on both sides of the equation:
The 3x's will cross out on the right side of the equation
3x-3x=0x=0
On the left side:
6x-3x=3x
SO, now the equation looks like:
3x=1
Now, to get x by itself, perform the opposite operation by dividing 3 on both sides of the equation:
The 3's will cross out on the left:
3x ÷ 3 = 1x = x
On the right:
1 ÷ 3 = 1/3
x=1/3
