Answer 1

Answer:

$\huge\mathcal{\fcolorbox{aqua}{azure}{\red{☃Answer}}}$

In this section, you will:

• Evaluate  2 × 2  determinants.

• Use Cramer’s Rule to solve a system of equations in two variables.

• Evaluate  3 × 3  determinants.

• Use Cramer’s Rule to solve a system of three equations in three variables.

• Know the properties of determinants.

We can use these formulas to solve for x and y but Cramer’s Rule also introduces new notation:

• D : determinant of the coefficient matrix

• Dx : determinant of the numerator in the solution of x .

$x = \frac{dx}{d}$

• Dy : determinant of the numerator in the solution of y.

$y = \frac{dy}{d}$
