Step-by-step explanation:
Have a good day :)
Equations:
Let x=the larger number
1. y=x-3
2. y=1/3(x+9)
Ok
2x + y - z = 7
-2y +3z = -15
x + 2y - 5z = 17
combine 2nd 3rd
x - 2z = 2
x = 2z + 2
double first statement
4x + 2y - 2z = 14
combine with second statement
4x + z = -1
substitute 2z + 2 for x
8z + 8 + z = -1
combine like terms
9z + 8 = -1
sub 8 from both sides
9z = -9
divide both sides by 9
z = -1
substitute -1 for z in second statement
-2y - 3 = -15
add 3 to both sides
-2y = -12
divide both sides by -2
y = 6
substitute -1 for z into the fifth statement
x = -2 + 2
x = 0

Answer:
x = 0
Step-by-step explanation:
Since we cannot divide by 0, the value of x which results in a denominator that is 0 is a value excluded from the domain;
This value can be found by setting the denominator equal to 0;
In this case, it is very simple as the denominator expression is simply "x", so the exluded value is: x = 0.
