Solve the following systems of equations express the answer as an ordered pair in the format (a, b) with no spaces between the numbers or symbols 2x7y=-7 and -4x-3y=-19

(7, -3)

Step-by-step explanation:

The correct system is 2x+7y=-7 and -4x-3y=-19.

Equation (1) will be , and equation (2)

Let's solve our system of equations using elimination:

Step 1. Multiply equation (1) by 2 and add the result to equation (2) and solve for y

 4x + 14y = -14) +

-4x - 3y = -19

‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾

       11y = -33

        equation (3)

Step 2. Replace equation (3) in equation (1) and solve for x

We can conclude that the solution of the system of equations is (7, -3)
