Question

Solve the inequality, SHOW WORK, please help I'll give brainliest ​

Answer 1

1. x≤5 Work: 2x+9≤19 move the constant to the right then its 2x≤19-9, then subtract the numbers and it would be 2x≤10, then divide both sides of the inequality by 2 which gives you the final answer of x≤5

2. x≥19 Work: x-7≥12 move the constant to the right then its x≥12+7, then add the numbers and get your final answer of x≥19

3. x≤4 Work: Divide both sides of the inequality by -3 and flip the inequality sign and that gives you -3÷(-3)≤-12÷(-3) and divide that which gives you x≤4

4. x<-3 Work: move the constant to the right which gives you -5x>16-1, then subtract to get -5x>15 and divide both sides of the inequality by -5 and flip the inequality sign to get x<-3

Note: This Took Forever LOL

Answer 2

The answer is in the attached photo!

Remember these 2 rules:

1) when you bring an element to the other side of the equation it changes sign

2) x must always be positive and this is obtained by multiplying all the terms of the equation by -1
