Question

how to find equations step by step?​

Answer 1

Answer:

$2x + 3y =4 \\ x + 2y =5$

Step-by-step explanation:

Step-by-step explanation:

If determinant so obtained are as follows

$D= \left|</p><p>\begin{array}{cc}2&3 \\1& 2 \end{array}</p><p>\right|$

$D_x= \left|</p><p>\begin{array}{cc}4&3 \\5& 2 \end{array}</p><p>\right|$

$D_y=\left| \begin{array}{cc}2&4 \\1& 5 \end{array}</p><p>\right|$

Then

In Cramer's Rule

D is the coefficients matrix of x and y

So equation are

$2x + 3y =4 \\ x + 2y =5$

Hope it helps you.
