Question

please solve it for me ​

Answer 1

2x + y = 16. --a

3x - 2y = 3. --b

• multiplying eq a by 2

4x + 2y = 32 --c

• Adding eq c and b

3x - 2y = 3

+ 4x + 2y = 32

7x = 35

x = 35/7 = 5

x = 5

• substituting x = 5 in a

2 × 5 - y = 16

10 - 16 = y

-6 = y

(x, y) = (5, -6) is solution of above equation.
