Question

Which one of the following is a solution of the linear equation 5 + 4 = 6?

(a) 2, 1 (b) 1, 2 (c) −2, 1 (d) 2, −1​

Answer 1

Answer:

d) 2, -1

Step-by-step explanation:

5x + 4y = 6

Solve using options,

at x=2, y=1,

10 + 4 = 14 ≠ 6

at x=1, y=2,

5 + 8 = 13 ≠ 6

at x=-2, y=1,

-10 + 4 = -6 ≠ 6

at x=2, y=-1,

10 - 4 = 6
