Question

the sum of twice a number and 5 is at most 3 less than the number

Answer 1

So this is our inequality in algebraic terms: $2n+5\leq n-3$

Firstly, subtract n on both sides of the inequality: $n+5\leq -3$

Next, subtract 5 on both sides of the inequality, and your inequality is $n\leq -8$
