Question 250917: using substitution solve the problem 4c=3d+3 c=d-1 use detail please thank you
Answer by tutorcecilia(2152) (Show Source): You can put this solution on YOUR website!
4c=3d+3 c=d-1 [substitute c=d-1]
4(d-1)=3d+3 [use the distributive property to simplify]
4d-4=3d+3 [isolate the variable to one side of the equation]
4d-3d-4=3d-3d+3
d-4=3
d=3+4
d=7
.
Plug d=7 back into the original equation and solve for the c-term.
4c=3d+3
4c=3(7)=3
4c=24
c=24/4
c=6
.
So,
4c=3d+3
4(6)=3(7)+3
24=24 [checks out]
