If Americans spent $26 billion to remodel kitchens and bathroom. They spent $5 billion more on kitchens than bathrooms. How much was spent on each?
K + B = 26
K = B + 5
substitute the second eqution into the first in place of K and solve for B
(B+5) +B = 26
2B +5 = 26
2B = 26-5
2B = 21
B = 21/2 = 10.5 billion dollars
Now place the found bathroom value back in and solve for Kitchens
K = B + 5
K = 10.5 + 5
K = 15.5 billion dollars
check
K + B = 26
15.5 + 10.5 = 26
