Use the matrix tool to solve the system of equations. choose the correct ordered pair.3x - 8y = -1 -2x + 6y = 1 a.(1, 1/2) b.(1/2, 3) c.(1/2, 1) d.(3,1/2)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
