Question

5y+4x=14 solve these two equation x+y=16​

Answer 1

x=14-5y/4

14-5y/4+y=16

-5y+4y/4=16-42

-y=26*4

y=-104

x=14-5*-104/4

x=14+520/4

x=534/4

x=133.5

mark me brilliant please

Answer 2

Answer:

x = 66, y = -50

Step-by-step explanation:

5y + 4x = 14

x + y = 16

Multiplying the 2nd equation by 4.

5y + 4x = 14                    ...1

4x + 4y = 64                   ...2

Subtracting 2 from 1.

y = -50

Substituting value of y = -50 in 2.

4x + 4(-50) = 64

4x + (-200) = 64

4x - 200 = 64

4x = 200 + 64

    = 264

x = 264/4

x = 66

Hope this helps
