Numerous engineering and scientific applications require finding solutions to a set of equations. Ex: 8x + 7y = 38 and 3x - 5y = -1 have a solution x = 3, y = 2. Given integer coefficients of two linear equations with variables x and y, use brute force to find an integer solution for x and y in the range -10 to 10. Ex: If the input is: 8 7 38 -5 -1 Then the output is: 3 2 Use this brute force approach: For every value of x from -10 to 10 For every value of y from -10 to 10 Check if the current x and y satisfy both equations. If so, output the solution, and finish. Ex: If no solution is found, output: No solution You can assume the two equations have no more than one solution. Note: Elegant mathematical techniques exist to solve such linear equations. However, for other kinds of equations or situations, brute force can be handy.

Numerous engineering and scientific applications require finding solutions to a set of equations. Ex: 8x + 7y = 38 and 3x - 5y = -1 have a
solution x = 3, y = 2. Given integer coefficients of two linear equations with variables x and y, use brute force to find an integer solution for x
and y in the range -10 to 10.
Ex: If the input is:
7
38
3
-5
-1
Then the output is:
3 2
Use this brute force approach:
For every value of x from -10 to 10
For every value of y from -10 to 10
Check if the current x and y satisfy both equations. If so, output the solution, and finish.
Ex: If no solution is found, output:
No solution
You can assume the two equations have no more than one solution.
Note: Elegant mathematical techniques exist to solve such linear equations. However, for other kinds of equations or situations, brute force
can be handy.

Code:

#Read Equation-1 data
print("Equation-1 Inputs: ")
a = int(input("Coeff of X: "))
b = int(input("Coeff of Y: "))
c = int(input("Constant: "))

#Read Equation-2 data
print("\nEquation-2 Inputs: ")
d = int(input("Coeff of X: "))
e = int(input("Coeff of Y: "))
f = int(input("Constant: "))

#Create a flag with value false
flag = False

#Looping to find an integer solution for x
#and y in the range -10 to 10.
for x in range(-10, 11):
    for y in range(-10, 11):
        #if solution found
        #print solution and set flag to true
        if a * x + b * y == c and d * x + e * y == f:

            flag = True
#If flag is false then print NO SOLUTION
if not flag:
    print("\nNo solution")
