Find the solution to this system:
equation 1: 5x – 2y = -11
equation 2: -2x + 5y = 17
step 1: to create x-coefficients that are additive inverses,
equation 1 can be multiplied by y.

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol
