Given this matrix equation: [3 x x^2 -y 7y 2] -[6 1 x y 8 4] = [ -3 x-1 6 -2y 6 -2] Choose the equation that you can use to solve for x: 3-6=-3 x-1=x-1 x^2-x=6 -y-y=-2y

it's both, now can you answer my most recent question?

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
