 x + 2  =  5x/2 - (8x - 5)/4

Multiply each side by 4:

4[x + 2]  =  4[5x/2] - 4[ (8x - 5)/4 ]

Using the distributive principle and simplifying fractions:

4x + 8  =  2(5x) - (8x - 5)

4x + 8  =  10x - 8x + 5

4x + 8  =  2x + 5

Subtract 2x from both sides:

2x + 8  =  5

Subtract 8 from both sides:

2x  =  -3

Divide both sides by 2:

x  =  -3/2
