5 x 2 = 10
3) New fraction

9/10 is answer
9/10 can not be simplified. It is already in reduced form.
1) 8x-13
2)19r-19s
3)8m-10n
Solve in the parentheses then label the ones with the same variable and solve those setting up the equation with variable first. Do check this I am not perfect.
Hope this helped! ;)
5n - 1 < 24 is the inequality in question. Add 1 to both sides, obtaining:
5n < 25. Divide both sides by 5, obtaining n < 5 (answer)
