Answer:

See explanation

Step-by-step explanation:

Step 1. Substitute for d to solve for n:

From the first equation:

$d=70-n$

Then substitute it into the second equation:

$0.1(70-n)+0.05n=5.5\\ \\7-0.1n+0.05n=5.5\\ \\7+(-0.05n)=5.5\\ \\-0.05n=5.5-7=-1.5\\ \\n=\dfrac{-1.5}{-0.05}=30$

Step 2: Substitute for n to solve for d:

$d+n=70\\ \\d+30=70\\ \\d=70-30=40$
