I used a calculator and everything
Answer:
1680 ways
Step-by-step explanation:
Permutation has to do with arrangement
If a contractor builds homes of 8 different models and presently has 4 lots to build on, the number of ways he can arrange his homes is expressed as;
8P4 = 8!/(8-4)!
8P4 = 8!/4!
8P4 = 8*7*6*5*4!/4!
8P4 = 8*7*6*5
8P4 = 1680
Hence the can arrange his homes 1680 ways
If solving by elimination do this:
1.Add both rows together
-5x =45
2. Solve for x
x=-9
3. Substitute x into either equation (I will use y=7x+67)
y=7(-9)+67
y=4
4. Get variables
x=-9, y=4
