0.05n + 0.1d = 3.10
n + d = 44

d = 44 - n

Substituting to the first equation:

0.05n + 0.1(44 - n) = 3.10
0.05n + 4.4 - 0.1n = 3.10
-0.05n = 3.10 - 4.4
n = 26

Obtaining the value of nickels:
26 * 0.05 = 1.3

Therefore, the value of nickels that Bethany has is $1.30

Answer:

See below

Step-by-step explanation:

Do you mean -12(x+5)=-10?

Divide both sides by -12 -> x+5=10/12

Subtract 5 on both sides -> x=10/12-5 -> x=-4 1/6

So x=-4 1/6

Let me know if this wasn't the right equation
