Answer 1

Answer:

x = 3.

y = -2.

Equation :- 2x - 13y = k

TO FIND :-

K = ?

SOLUTION :-

★ x = 3.

★ y = -2.

☢ ACCORDING TO QUESTION ☢

→ 2x - 13y = k

→ k = 2x - 13y

★ Substitute all the values,

→ k = 2 × 3 - 13 × (-2)

→ k = 6 - (-26)

→ k = 6 + 26

→ k = 32

∴ The Value of k is 32.

★ VERIFICATION ★

→ 2x - 13y = k

→ k = 2x - 13y

★ Substitute all the values,

→ 32 = 2 × 3 - 13 × (-2)

→ 32 = 6 - (-26)

→ 32 = 32

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

HENCE VERIFIED.

Answer 2

Answer:

K=32

Explanation:

2x-13y=k

2(3)-13(-2)=k   [putting values of x and y respectively]

6+26=k

k=32
