(D)
Penjelasan dengan langkah-langkah:
xA = B + C
x [2...1] = [2...7] + [1...-5]
...[3...2]....[5...8] + [-4..-4]
x[2...1] = [3...2]
..[3...2]....[1...4]
x = [3...2] × 1/(4 - 3) [2...-1]
......[1...4]..................[-3...2]
x = [3...2] × 1/1 × [2...-1]
......[1...4]..............[-3...2]
x = [3...2] × [2...-1]
......[1...4]....[-3...2]
x = [3(2) + 2(-3)....3(-1) + 2(2)]
......[1(2) + 4(-3)....1(-1) + 4(2)]
x = [6 - 6.....-3 + 4]
......[2 - 12...-1 + 8]
x = [0......1]
......[-10...7] (D)
