Question

5x – 3y = 2

4x + 7y = −3​

Answer 1

Answer:

-23/47

Step-by-step explanation:

5x-3y=2

5x=2+3y

x=2+3y/5

A/S

4(2+3y/5)+7y=-3

(8+12y/5)+7y=-3

8+12y+35y/5=-3

8+12y+35y=-15

8+47y=-15

47y=-23

y=-23/47

Answer 2

Step-by-step explanation:

5x - 3y = 2 ---------(1)

4x + 7y = -3 --------(2)

multiply equ 1 by 4 and 2 by 5,

we get,

20x - 12y = 8 ---------(3)

20x + 35y = -15 ------(4)

now, subtracting equation 4 from 3,

we get,
