Please give me correct answer.​

Answer 1

Answer:

hey here is your answer

pls mark it as brainliest

Step-by-step explanation:

so let 2x+3y=11 (1)

& 2x-4y=-24 (2)

so subtracting (2) from (1)

we get

7y=35

ie y=5

substitute value of y in any of two equations

we get

x=-2

hence (x,y)=(-2,5) is solution of above linear equations

Answer 2

Answer:

(-2, 5)

Step-by-step explanation:

according to cross multiplication method

b1. c1. a1. b1.

b2. c2. a2. b2

3 -11. 2. 3

-4. 24. 2. -4

b1c2 - b2c1 c1a2 - c2a1

x = __________ y = ___________

a1b2 - a2b1. a1b2 - a2b1

72 - 44

_______ = x. y= -22 - 48

-8 - 6. ________

-14

x = 28/-14 y= -70/-14

x= -2. y= 5
