**4611star**, Sunday, January 29, 2012 at 10:36am4x-15/2=1/2

2*1/2=1

4x-15=1

4x=1+15

4x= 16

x= 16/4

x= 4

**Jai**, Sunday, January 29, 2012 at 10:43am4x - 15/2 = 1/2

first we transpose all terms with no variable x to the right side of equation. that is, we transpose - 15/2 to the right. note that when we transpose, we change the sign to its opposite. thus is becomes positive:

4x = 1/2 + 15/2

when adding fractions, we first check if their denominators are the same. if they are the same, we can readily add the numerators. thus,

4x = 16/2

4x = 8

to get x alone, we divide both sides by the numerical coefficient or the number before the variable x (which is 4). thus,

x = 8/4

x = 2

hope this helps~ :)
