You add 1/2 to each side to get x=1.

dont get it

\[\frac{ 1 }{ 2 }=x - \frac{ 1 }{ 2 }\] this is our given. if we are to look for the value of x, then we need to isolate it first. it can be isolated either on the right-hand-side (RHS) or left-hand-side (LHS). This time, it is more convenient to isolate it on the RHS. We can achieve this by adding 1/2 on both sides of the equation (LHS and RHS). If we did this, it would cancel out the -1/2 on the RHS and it would leave the x alone by itself. meanwhile, the LHR we would have 1/2 + 1/2 now giving us 1. Finally, our equation would look like this: \[\frac{ 1 }{ 2 }+ \frac{ 1 }{ 2 } = x - \frac{ 1 }{ 2 } + \frac{ 1 }{ 2 }\] \[\frac{ 2 }{ 2 } = x \] 2/2 is the same as 1 therefore: 1 = x
