1) Concept:

Any ordered pair is said to be the solution for the given equation only if it satisfies the equation on by substitution.

2) Calculation:

Given,

Ordered Pair:(12, 910)

Equation: 5y−4=x

For the ordered pair (12, 910) we have x=12 and y=910, which on substitution in the given equation, we have

5y−4=x

5(910)−4=12

92−4=12

9−82=12

12=12 which is true.

Hence, the ordered pair (12, 910) is the solution of the given equation 5y−4=x.

Final statement:

Therefore, (12, 910) is the solution of the equation 5y−4=x.
