Answer 2

Step-by-step explanation:

By using elimination method,

5x + 7y = 17 ______(1)

3x - 2y = 7 _______(2)

Multiply, equation (1) by 3 and equation (2) by 5.

{(5x+7y=17)} ×3

⟹ 15x + 21y = 51 _____(3)

{(3x-2y=4)}) × 5

⟹ 15x - 10y = 20 _____(4)

Subtract equation (4) from (3),

15x + 21y = 51

15x (+) - 10y = (-)20

_________________

31y = 31

31

31

⟹ y = 1

Now, put the value of y in eq (1),

5x + 7(1) = 17

⟹ 5x + 7 = 17

⟹ 5x = 17 - 7

⟹ 5x = 10

⟹ x = {10}{5}

5

10

⟹ x = 2
