Answer 2

$\huge\underline\bold\red{Answer}$

Given :-

• 7x + 5y = 46

• 5x + 7y = 50

To Find :-

• Value of x and y

__________________________

7x + 5y = 46 _____1)

5x + 7y = 50 _____2)

Add equation 1) and 2)

x + y = 8 _____3)

Subtract equation 2) from 1)

x - y = -4 _____4)

Add equation 3) and 4)

x + y = 8

x - y = -4

=> 2x = 8 + (-4)

=> 2x = 8 - 4

=> 2x = 4

=> x = 2

Put the value of x in equation 3)

x + y = 8

=> 2 + y = 8

=> y = 8 - 2

=> y = 6

Hence, the values of x and y are 2 and 6 respectively.
