Answer:
D = 4, Z = 24
Step-by-step explanation:
6D+3Z = 96
5D+4Z = 116
multiply top by 5 and bottom by -6
top equation = 30D+15Z = 480
bottom equation = -30D-24Z = -696
Cancel 30D and -30 D
top equation = 15Z = 480
Bottom equation = -24Z = -696
15Z - 24 Z = 480 - 696
-9Z = 216
Z = 216/9
Z = 24
Now that we have the value of Z, we can substitute it in any equation to find D
6D + 3(24) = 96
6D + 72 = 96
6D = 96 - 72
6D = 24
D = 24/6
D = 4

Answer:
194
Step-by-step explanation:
Recall 2 rules to solve this easily:
1. 
2. 
<em>Now, if we let a = 7 and 
, we can say the problem is basically of the form:</em>
This can be simplified using the rules:
Now we can plug the values of a and b we initially thought of (remember though 
):
194 is the final answer.
