Use Cramer's rule to find the solution to the following system of linear equations.

slavikrds [6]

Answer:

x = 53

y = 30

Step-by-step explanation:

Step(I):-

Given equations are

x -2y =-7 ...(I)

5x-9y =-5 ..(ii)

The matrix form AX = B

$\left[\begin{array}{ccc}1&-2\\ 5 & -9\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}-7\\-5\\\end{array}\right]$

The determinant

$= \left|\begin{array}{ccc}1&-2\\5&-9\\\end{array}\right| = -9+10 =1$

By using Cramer's Rule

Δ₁ = $\left[\begin{array}{ccc}-7&-2\\\\-5&-9\end{array}\right]$

The determinant is Δ₁ = -9 X -7 - (10 ) = 53

x = Δ₁ / Δ

x = 53

The determinant

Δ₂ =

Δ₂ = -5 +35

y = Δ₂/Δ = 30
