Question

if x€I find solution set of 10-2(1+4x)is less than20​

Answer 1

$10-2(1+4x)<20\\\\10-2-8x<20\\\\8-8x<20\\\\8-8x-8<20-8\\\\-8x<12\\\\\frac{-8x}{-8}<\frac{20}{8}\\\\x<\frac{20}{8}\:\:\:\:or,\:x<2.5$

Hence, The solution set (for the value of x) of the given linear inequation is {.....-2, -1, 0, 1, 2, 2.5}
