Answer:
0.625
Step-by-step explanation:
Fractions are another way to show two numbers being divided. The top number of the fraction (numerator) is divided by the bottom number (denominator).
In this case, it would be 5 divided by 8.
This equals 0.625, making 0.625 your answer.

I prefer using the RREF function to put the augmented matrix into reduced row-echelon form. If the equations are dependent or inconsistent, using that method tells you so without giving a matrix inversion error.
Let b>a...
b=2(a+4)
b=2a+8 then we are told that:
b-a=11 using b found above in this equation gives you:
2a+8-a=11 combining like terms on left side
a+8=11 subtracting 8 from both sides
a=3
So the smaller number is 3.
...
since b=2a+8
b=14
check..
b=2(a+4)
14=2(3+4)
14=2(7)
14=14
and
b-a=11
14-3=11
11=11
