remember that you can do anything to an equation as long as you do it to both sides
with inequalities, if you multiply or divide bth sides by a negative number, flip the direction of the inequality sign (ex < to >)
1.
m-7<6
add 7 to both sides
m+7-7<6+7
m+0<13
m<13 is answer
4th option
2.
n-8>5
add 8 to both sides
n+8-8>5+8
n+0>13
n>13 is answer
1st option
3.
p+5<10
minus 5 both sides
p+5-5<10-5
p+0<5
p<5 is answer
2nd option
4.
students+adults≤bus capacity
20+?≤35
solve
minus 20 both sides
20-20+?≤35-20
0+?≤15
?≤15
max number is 15
answers:
1. m<13
2. n>13
3. p<5
4. 15
