♡⚘✮ʜᴇʏᴀ ᴍᴀᴛᴇ ʜᴇƦᴇ ɪֆ ʏᴏᴜƦ ᴀɴֆᴡᴇƦ :

$\frac{1}{7x} + \frac{1}{6y} = 3...(1) \\ \frac{1}{2x} - \frac{1}{3y} = 5...(2) \\ \\ multiplying \: (1) \: by \: 42 \: and \: (2) \: by \: 6 \\ we \: get \: \\ \\ = 6x + 7y = 126...(3) \\ = 3x - 2y = 30...(4) \\ \\ on \: solving \: this \: both \: (3).(4) \: eqn \: \\ we \: get \: \\ x = 14. \: \\ y = 16$

Answer 2

Answer:

x=12 and y= -3

Step-by-step explanation:

1/2×(1/2x-1/3y=5)

it become

1/7x+1/6y=3. eq 1

1/4x-1/6y=5/2. eq 2

adding both the equations

1/7x+1/6y+ 1/4x-1/6y = 3+5/2

1/7x+1/4x = 3+5/2

11x = 132

x = 12

now

put the value of x in eq 2 or 1

1/2×12 + 1/3y = 5

y = -3
