write and solve an inequality for following statements: ten minus the sum of s and 3 is less then twenty
10 - ( s + 3 ) < 20
10 - s - 3 < 20
7 - s < 20 Subtract 7 to both sides
7 - s - 7 < 20 - 7
- s < 13
Multiply both sides by - 1
If you multiplied or divided both sides of an inequality by the negative number, then you must reverse the inequality sign.
s > - 13
