Question

please mujhe iska answer dedo please ​

Answer 1

Answer:

x = -18/5 ; y = 2

Step-by-step explanation:

5x - 6y + 30 = 5x + 4y -20 = 0

5x - 6y + 30 -5x - 4y +20 = 0

cancelling 5x and -5x

-6y -4y + 20 = 0

-10y + 20 = 0

-10y = -20

y = 2

substituting y = 2

5x - 6(2) + 30 = 0

5x -12 + 30 = 0

5x + 18 = 0

5x = -18

x = -18/5

hope it helps you

Answer 2

Answer:

3) 5x-6y+30=0

5x+4y-20=0

-__-__+______

-10y+50=0

-10y=-50

y=5

5x-6y+30=0

5x-6×5+30=0

5x-30+30=0

5x=0

x=0

5) 3x+y=10

x-y=2

_________

4x=12

x=3

x-y=2

3-y=2

-y=2-3

y=1

Step-by-step explanation:

hope you understand and it helps you.
