Answer 1

Step-by-step explanation:

3x-2y=7. x-2y=-3. ______ 2x = 4. x=2. y= -1/2

Answer 2

___________________________________

ǫᴜᴇsᴛɪᴏɴ :-

3x - 2y = 7

x - 2y = -3

___________________________________

sᴏʟᴜᴛɪᴏɴ :-

=> x - 2y = -3

=> x = -3 + 2y

ᴘᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇ ᴏғ x ɪɴ ғɪʀsᴛ ᴇǫᴜᴀᴛɪᴏɴ

=> 3(-3 + 2y ) -2y = 7

=> -9 + 6y -2y = 7

=> 4y = 16

=> y = 16/4

___________________________________

Y = 4

___________________________________

again

=> x - 2y = -3

=> x - 2(4) = -3

=> x = -3 + 8

___________________________________

X = 5
