2x = 1/2(x+1) Multiply by 2 to get rid of the fraction.
4x = x+1 Get x all on one side of the equation.
3x = 1 Divide by 3.
x = 1/3

Multiply the whole equation by 2 to get
4x = x + 1
Transfer x to the left side to get
4x - x = 1
3 x = 1
Multiply the equation by 1/3 to get
x = 1/3
Substitute 1/3 for x , 1/3 is about 0.3333
2 (0.3333) = 0.3333 + 1 over 2
0.6667= 1.3333 / 2
0.6667 = 0.6667

Divide both sides by 2, to get x=1/4(x+1), Distribute the 1/4 to get x = 1/4 x +1/4, subtract 1/4x from both sides to get 3/4x=1/4, Multiply both sides by 4/3, to get x= 1/3

2x = 1/2(x+1)
2x = 1/2x + 1/2
2x-1/2x = 1/2
3/2x = 1/2
6x = 4
x = 4/6
x = 2/3

2x = 1/2(x + 1)
2(2x) = 2(1/2)(x + 1)
4x = x + 1
4x - x + x + 1 - x
3x = 1
3x / 3 = 1 / 3
x = 1 / 3

2x=1/2x+1/2
the denominator is common in the right side so we cross multiply.
2*2x=1x+1
4x=1x+1
Transfer 1x to the other side
4x-1x=1
3x=1
x=1/3
