Question

Which of the following ordered pairs represents a solution to the equation4x - 2y = -10 *

Answer 1

This question is about linear equations with two variables.

The solution to this type of equation is an ordered pair.

To know which pair is the solution, we need to substitute each of them in the given equation in order to get a true answer.

The given equation is

`4x-2y=-10`

First pair (1/2, 6). Let's replace each value

`4((1)/(2))-2(6)=-10`

Then, we solve each part and see if we get a true answer

`(4)/(2)-12=-10\rightarrow2-12=-10\rightarrow-10=-10`

AS you can observe, the pair gave us a true answer, because -10=-10 is absolutely true, this means this pair is a solution of the given equation.

Therefore, the right answer is

`((1)/(2),6)`
