4.3x+%2B+23.0+%3E+57.5+-+7.2x Start with the given inequality


43x+%2B+230+%3E+575+-+72x Multiply both sides by 10 to move the decimal to the right. This will eliminate the decimals.



43x%3E575-72x-230Subtract 230 from both sides


43x%2B72x%3E575-230 Add 72x to both sides


115x%3E575-230 Combine like terms on the left side


115x%3E345 Combine like terms on the right side


x%3E%28345%29%2F%28115%29 Divide both sides by 115 to isolate x



x%3E3 Divide
