Use a transformation to solve the equation. d-(-17)=-14

jimthompson5910 (jim_thompson5910):

subtracting a negative is the same as adding so d-(-17) is the same as d+17

jimthompson5910 (jim_thompson5910):

we now have this equation: d+17 = -14 how do we isolate d?

OpenStudy (anonymous):

-31 ?

jimthompson5910 (jim_thompson5910):

you are correct

jimthompson5910 (jim_thompson5910):

you subtract 17 from both sides to get d = -31
