Solve the inequality 81-1 1/5x<55

{x:x<11/130}

Step-by-step explanation:

given 81-1 1/5x<55. you first change the < to equal sign (=)

given you 81-11/5x=55. multiplying throughout the equation with 5x.

thus, 81*5x - 11/5x * 5x = 55*5x

results to 405x-11=275x

grouping like terms.

405x-275x=11 results to

130x = 11

dividing through by 130

you will get x = 11/130. The inequality is written as {x:x<11/130}. the
