Question

Solve the inequalities. 1. 3t ≤ 27 2. y - 5 ≥ 0 3. x + 4 < 10

Answer 1

Solving an inequality is just like solving a normal two step equation.

1. T is less than or equal to 9.

2. y is greater than or equal to 5.

3. x is less than 6.

Answer 2

1. 3t<=27 so divide 3 on both sides to get t=9
2. y-5>=0 so add 5 to 0 and get y=5
3.x+4<10 so subtract 4 from 10 to get x=6
Always undo addition,subtraction,multiplication and division and always do it on both sides!
