You can put this solution on YOUR website!
one-third(d+9)=-12; what's d??
%281%2F3%29%28d%2B9%29+=+-12
Mult equation by 3 and you have:
d+9 = -36
d = -36 - 9
d = -45
:
You should check the solution in the original equation:
%281%2F3%29%28-45%2B9%29+=+-12
%281%2F3%29%28-36%29+=+-12
:
:
4.5-1.5(6m+2)= 6; what's m??
Mult what's inside the brackets:
4.5 - 9m - 3 = 6
1.5 - 9m = 6
-9m = 6 - 1.5
-9m = 4.5
m = 4.5/-9
m = -.5
:
Check solution:
4.5 - 1.5(6(-.5)+2) = 6
4.5 - 1.5(-3+2) = 6
4.5 - 1.5(-1) = 6
4.5 + 1.5 = 6
