Solve the following system of equations. express your answer as an ordered pair in the format (a, b), with no spaces between the numbers or symbol. 2x+7y=4 -4x-3y=14

The correct ordered pair to solve this system of equations is (-5, 2).

You can find this by using elimination. Start by multiplying the first equation by 2. Then you can add the two equations together and the x values will drop out. This allows you to solve for y like so:

4x + 14y = 8
-4x - 3y = 14

11y = 22
y = 2

Then you can use that value for y in either equation to find the x value. 

2x + 7y = 4
2x + 7(2) = 4
2x + 14 = 4
2x = -10
x = -5

C. a,b, and d are not numbers. they are expressions.
