Which statements about this system of equations are true? Choose three correct answers. 2 x minus 7 y is equal to negative 13 negative 2 x plus 11 y is equal to 1

Adding the equations cancels the x-terms: (2x − 2x) + (−7y + 11y) = −13 + 1, giving 4y = −12. Thus y = −3, so the x-variable is eliminated and the sum is 4y = −12. The true statements are that x is eliminated, y equals −3, and the sum is 4y = −12.
