What is the y-value of the solution to the system of equations?3x + 5y = 17x + 4y = −13

Read the system as 3x + 5y = 1 and 7x + 4y = −13. Multiply the first equation by 7 and the second by 3: 21x + 35y = 7 and 21x + 12y = −39. Subtracting the second equation from the first gives 23y = 46, so y = 2. The correct choice is 2.
