hi,
 first....simplify the brackets
what will u get ?

anonymous · Answer

brackets meaning either sides of the > or the [1+2(x-1)]

***[isuru]*** · Answer

$$2(4x + 2) > -5[1 + 2(x -1)]$$
$$ 8x + 4 > -5[1 + 2x -2]$$
$$ 8x + 4 > -5[2x -1]$$
$$ 8x + 4 > -10x +5$$
$$ 18x  > 1$$
 $$ x  > 1/18$$

did u get it ?
