Answer:
b=9,a=12
Step-by-step explanation:
I solved by substitution:
b = 3/4a ---> plug this into the other equation
a + b = 21 is now a + 3/4a = 21
Reduce: 7/4a = 21
a = 12
Now solve for b:
b=3/4a is now b=3/4(12)
b=9

// Function to perform division (x / y) of two numbers x and y. // without using division operator in the code. int divide(int x, int y)
{ // handle divisibility by 0. if (y == 0)
{ printf("Error!! Divisible by 0"); exit(1);
} // store sign of the result.
int sign = 1; if (x * y < 0)
