Question

16x − 7 ≤ − 71

Find the solution set of the inequality

Answer 1

x
`\leq -4\\`

Explanation:

Add 7 to other side making equation 16x
`\leq`-71+7

16x
`\leq`-64

16 goes into -64 -4 times.

Answer would give you x
`\leq`-4

To check, you could substitute -4 into the inequality

16(-4)-7
`\leq`-71

-71
`\leq`-71 check

16(-10)-7
`\leq`-71

-167
`\leq`-71 check
