Question

if 2x+y=12 and 3x-y=13 find the value of x​

Answer 1

Required Answer:-

Given:

• 2x + y = 12
• 3x - y = 13

To find:

• The value of x.

Solution:

Given that,

➡ 2x + y = 12 ......(i)

➡ 3x - y = 13 ......(ii)

Adding both equations (i) and (ii), we get,

➡ 2x + y + 3x - y = 12 + 13

➡ 5x = 25

➡ x = 25/5

➡ x = 5

Hence, the value of x is 5.

Answer:

• The value of x is 5.

❥︎ Tʜᴇ Gɪᴠᴇɴ Eǫᴜᴀᴛɪᴏɴs ᴀʀᴇ:

2x + y = 12 ———— (i)

3x - y = 13 ———— (ii)

❥︎ Aᴅᴅ Eǫᴜᴀᴛɪᴏɴ (i) & (ii):

➪ 2x + y + 3x - y = 12 + 13

➪ 5x = 25

➪ x = 25 / 5

➪ x = 5

❥︎ Pᴜᴛ ᴛʜᴇ Vᴀʟᴜᴇ Oғ "x" ɪɴ Eǫᴜᴀᴛɪᴏɴ (i):

2x + y = 12

2(5) + y = 12

➪10 + y = 12

➪ y = 12 - 10

➪ y = 2
