Question

Which ordered pair is the solution?

Answer 1

Answer:

Option d.

Step-by-step explanation:

The given equation is

$7x-5=4y-6$

We need check which ordered pair is the solution.

Substitute x=2 and y=4 in the above equation.

$7(2)-5=4(4)-6$

$14-5=16-6$

$9=10$

It is a false statement because $9\neq 10$.

So, (2,4) is not a solution of given equation.

Substitute x=3 and y=6 in the above equation.

$7(3)-5=4(6)-6$

$21-5=24-6$

$16=18$

It is a false statement because $16\neq 18$.

So, (3,6) is not a solution of given equation.

Therefore, option d is correct.

Answer 2

Answer:

d) neither

Step-by-step explanation:

Given equation is 7x - 5 = 4y -6 ...…...... (1)

Substitute x = 2 and y= 4 in equation (1)

 7(2) -5 = 4(4) -6

  9 ≠ 10

a) is not satisfied

Substitute x = 3 and y= 6 in equation (1)

 7(3) -5 = 4(6) -6

  16 ≠ 18

b) is not satisfied

c) is also not satisfied

Final answer:- neither
