Let x+y=10 be equation (1)
and y=x-4 be equation (2)
from (2)
y=x-4...(3)
sub (3) into (1)
x+(x-4)=10
x+x-4=10
2x=12
x=6
sub (x) into (3)
y=6-4
y=2
Answer:
r=12 as answer but as you will have reflective numbers (r12+2)(10x10)=3 in this sort of equation you will see that as they grew at a 88.3% rate 5/6 and 0.16 is a per month rate the coefficient value we can round down and call r12 = 6 for step 2 in the equation. As we can also find +0.88 which rounds to 1 and 0.33 the rate of change per month rounds to -1 and -100/12=8.3 if you are looking for the percentage. To find 6 we only need to 10/10 = 1. It is important you keep an equation simple for the growth as the change in measurement will always need a new percentage and we have a base number that can show such percentage as if it changed to 100% again at 12 inches we could reuse the equation =3-2=1 etc. or r12/100 =0.88 r=rise percentage and also be divided into 2 if we call r12 and r2 in same first equation to make r6.
