The quotient of x^+ x-6/x^2 -6x +5 / x^2 + 2x -3/x^2 -7x +10 has in the numerator and in the denominator

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
