Answer 1

scanf needs & before a[]

https://stackoverflow.com/questions/44789110/getting-values-for-an-array-using-scanf-function-in-c

a[i][j] //this hold the pointer of element in the array
&a[i][j] //this is the place of the value of the element in the array

scanf("%f",&a[i][j]);
scanf("%f",&b[i]);

Answer 2

First of all take input then scan the value.
store it by using "&"
without "&" it will show you the garbage value...
give upvote if I solved your problem...

#include <stdio.h>
int main()
{
int i,j,k;
float a[5][5], b[5], x, y, z, q, p;
printf ("Hello, assume linear equation as (ax + by = c)\n");
for(i = 0; i < 2; i++)
{
for (j = 0; j < 2; j++)
{
printf ("Enter the co-efficients of x and y respectively:\t");
scanf("%f",&a[i][j]);
}
printf ("\n");
}
for(k = 0; k < 2; k++)
{
printf ("Enter constant values respectively:\t");
scanf("%f",&b[k]);
}

x = (a[0][0] * a[1][1]) - (a[1][0] * a[0][1]);

y = (b[0] * a[1][1]) - (b[1] * a[0][1]);

z = (a[0][0] * b[1]) - (a[1][0] * b[0]);

p=y/x;
q=z/x;

printf ("\nDelta=\t%f",x);
printf ("\nDeltax=\t%f",y);
printf ("\nDeltay=\t%f",z
