For what value of (y) is 3^3/3^y =1/9

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2
