Question

5x +2y=-3, x+5y=4


10th equations please answer me​

Answer 1

Answer:

5x+2y=-3

5x+25y=20

subtract

23y=23

y=1

put value of y in equation 1

then,

5x+2=-3

5x=-5

X=-1

then,y=1 and X=-1

Answer 2

Step-by-step explanation:

VERY EASY

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

x+5y=4

x = 4-5y .....(2)

From (1):

5x + 2y = -3

5(4-5y) + 2y = -3 [from 2]

20 - 25y + 2y = -3

23 = 23y

y = 1

x = 4-5y

= 4-5 = -1
