Answer:
- D = -87
- Dx = 174
- Dy = -435
- Dz = 0
- (x, y, z) = (-2, 5, 0)
Step-by-step explanation:
The determinant of the coefficient matrix is ...
The other determinants are found in similar fashion after substituting the constants on the right for each of the above matrix columns, in turn.
Those determinants are ...
The solutions are ...
x = 174/-87 = -2
y = -435/-87 = 5
z = 0
That is, (x, y, z) = (-2, 5, 0).
The expression which is equivalent to the provided expression of variable x is,
Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
The given expression in the problem is,
Let the equivalent expression of this expression is f(<em>x)</em>. Thus,
The number, with negative power, can be written in the fraction of 1 with the same but positive power or exponent. Therefore,
Solve it further as,
Hence, the expression which is equivalent to the provided expression of variable x is,
