Which statement about the ordered pairs (−9, 3) and (2, −4) is true for the equation 6x−y/2=14
a)both ordered pair are solutions
b)neither ordered pair are solutions
c) (2,-4) is a solution to the equation
d) (-9, 3) is a solution to the problem.

Keywords:

equation, variables, ordered pairs, solution

For this case, an equation with two variables, "x" and "y" respectively, given by: . We must say which of the given statements is true, having as data the following ordered pairs : To know if the ordered pairs are equation solution , we must replace the values of x and y in the equation and observe if equality is met, if it is met, then the chosen pair is the solution of the equation.

So:

We substitute

It is observed that the equality is not met, so is not a solution of the given equation.

We substitute

We take into account that

It is observed that the equality is fulfilled, thus, is a solution of the given equation.

Option C

(2, -4) is a solution to the equation

y = x + 95

y = 42 + 95

y=137 mm hg
