can you solve (x/1) divide by (3/x +1/x)

Given: x + y = 6. if xe (-15, -6, -1), then which of the following sets of ordered pairs are solutions? © {(-15, -21), (-6, -12), (-1, -7)} [(-15, 21), (-6, , 7)} {(-15, 21), (-6, 12), (-1, -7)}

Write the expression in complete factored form. 5n_(c - 3) - n(c - 3) =

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x
