Answer 2

$\Large{\underline{\underline{\mathfrak{\red{\bf{Solution}}}}}}$

$\Large{\underline{\mathfrak{\orange{\bf{Given}}}}}$

• 2x-3y =12________(1)
• 2x +4y = -2_______(2)

$\Large{\underline{\mathfrak{\orange{\bf{Find}}}}}$

• Value of x & y

$\Large{\underline{\underline{\mathfrak{\red{\bf{Explanation}}}}}}$

Subtract equ(1) &equ(2)

➡ -3y - 4y = 12 + 2

➡-7x = 14

➡x = 14/(-7)

➡x = -2

Keep value of x in equ(1)

➡2 × -2 - 3y = 12

➡-3y = 12 + 4

➡-3y = 16

➡y = 16/(-3)

➡y = -16/3

$\Large{\underline{\mathfrak{\orange{\bf{Hence}}}}}$

• Value of x = -2
• Value of y = -16/3

$\Large{\underline{\underline{\mathfrak{\red{\bf{Answer\:Verification}}}}}}$

Keep Value of x & y in equ(1)

➡2 × -2 - 3 × -16/3 = 12

➡-4 + 16= 12

➡12 = 12

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

We can say that our solution is right.
