Question

Solve 30x -12,000 less than or equal to 980

Answer 1

`\large\boxed{x\leq432(2)/(3)\to x\in\left(-\infty,\ 432(2)/(3)\right]}`

Explanation:

`30x-12,000\leq980\qquad\text{add 12,000 to both sides}\\\\30x-12,000+12,000\leq980+12,000\\\\30x\leq12,980\qquad\text{divide both sides by 30}\\\\x\leq(12,980)/(30)\\\\x\leq(1,298)/(3)\\\\x\leq432(2)/(3)`
