Answer 1

Answer:

x = y = 24/7

Step-by-step explanation:

See in the attachment.

Answer 2

❏ Solution

Given Equation:-

• 8x + 6y = 48 ....... [ .equ (1) ]
• 3x + 4y = 24 .......[ equ (2) ]

Multiply by 3 in (1) and 8 in (2)

• 24x + 18y = 144
• 24x + 32y = 272

____________________Sub. it

➩ - 14y = - 128

➩ y = -128/(-14)

➩ y = 64/7

[ keep value in equ(2) ]

➩ 3x + 4 × 64/7 = 24

➩ 3x = 24 - 256/7

➩ 3x = ( 168 - 256 )/7

➩ 3x = - 88/7

➩ x = -88/(7×3)

➩ x = -88/21

Thus:-

• Value of x = -88/21
• Value of y = 65/7

Answer Verification

[ Keep value of x and y in equ(2) ]

➩ 3 × -88/21 + 4 × 64/7 = 24

➩ -88/7 + 256/7 = 24

➩ ( -88 + 256 )/7 = 24

➩ 168/7 = 24

➩ 24 = 24

L.H.S. = R.H.S.

That's proved

So, we can say that our solution is correct
