Question

solve : x + 3y = 16
2x + 3y = 4​

Answer 1

Answer:

(x,y) = [(-8),8]

Step-by-step explanation:

x + 3y = 16.......(1)

2x + 3y = 4.......(2)

Subtract (1)&(2)

2x + 3y = 4

x + 3y = 16

- - -

______________

x = -8

substitute x=(-8) in (1)

x + 3y = 16

3y=24

y=8

(x,y) = [(-8),8]

Answer 2

Answer:

✅Here's your answer

$x + 3y = 16 \\ \\ x = 16 - 3y$

Substituiting the value of x in equation (ii)

$2x + 3y = 4 \\ \\ 2(16 - 3y) + 3y = 4 \\ \\ 32 - 6y + 3y = 4 \\ \\ - 3y = 4 - 32 \\ \\ - 3y = - 28 \\ y = \frac{28}{3}$

#So for x

$x = 16 - 3y \\ \\ x = 16 - 3 (\frac{28}{3} ) \\ \\ x = 16 - 28 \\ \\ x = - 12$
