What is the solution to the system of equations? y is equal to 2 x minus 3 point 5 x minus 2 y is equal to negative 14

Substitute y = 2x − 3.5 into x − 2y = −14: x − 2(2x − 3.5) = −14. Simplifying gives −3x + 7 = −14, so x = 7. Then y = 2(7) − 3.5 = 10.5, so the solution is 7 comma 10.5, choice B.
