Look at that website. The part says that (ab*ad)=(ac*ae)
Doing that, we get
9*(9+11x)=10(10+8x)
81+99x=100+80x
19x=19
X=1
Lets x and y are the value of two numbers.
x + y = 16
x - y = 2.4
If x + y = 16 then x = 16 - y
Substitute x = 16 - y into x - y = 2.4
16 - y - y = 2.4
16 - 2y = 2.4
2y = 13.6
y = 6.8
x = 16 - y
x = 16 - 6.8
x = 9.2
Answer:
The value of two numbers are 9.2 and 6.8
