Answer:
your answer is here jankishah...
30 - 4(2x - 1) > 8
30 - 8x +4 > 8
add (-4) on both side,
30 - 8x > 4
add -30 on both side,
-8x > -26
divide (-8) on both side,
x < -26/-8........( when we divide the (-) sign on both side, the sign will be changed)
x = 3.25
if we write it in set form the answer will be,
x ={ 1, 2 , 3}
why not 0, -1 , -2...etc.
note- because in question it is given as x belongs to the positive integers.
so no negative integers should be taken.
hope this will help you....
