Question

Which number line represents the solution to the inequality 3x−8≥7?

Answer 1

Look at the attached image below

Explanation:

`\tt 3x-8\ge \:7`

Add 8 to both sides:-

`\tt 3x\ge 7+8`

Add 7 and 8 to get 15:-

`\tt 3x\ge 15`

Divide both sides by 3:-

`\tt \cfrac{3x}{3}\ge \cfrac{15}{3}`

`\tt x\ge \:5`
