solve the equations:
1.) s - |-4| = 7.3
2.) p + 1.6 ÷ (-0.4) = -12

1) s - | -4 | = 7.3 

First, simplify | -4 | to 4. / Your problem should look like: s - 4 = 7.3 . 
Second, add 4 to both sides. / Your problem should look like: s = 7.3 + 4.
Third, simplify 7.3 + 4 to get 11.3. / Your problem should look like: s = 11.3, which is your answer.

2) p +  = -12

First, simplify  to  . / Your problem should look like: p +  = -12.
Second, simplify  to 4. / Your problem should look like: p - 4 = -12.
Third, add 4 to both sides. / Your problem should look like: p = -12 + 4.
Fourth, simplify -12 + 4 to -8. / Your problem should look like: p = -8, which is your answer.
