Sagot:
Solusyon: # x = 3, y = 43, z = -19 #
Paliwanag:
# 4x + y + 5z = -40 # (1)
# -3x + 2y + 4z = 1 # (2)
# x-y-2z = -2 # (3) #:. y = x-2z + 2 #
Paglalagay # y = x-2z + 2 # sa equaion (2) at (3) makuha namin, # 4x + x-2z + 2 + 5z = -40 o 5x + 3z = -42 # (4) at
# -3x + 2 (x-2z + 2) + 4z = 1 o -x = 1 -4:. x = 3 #
Paglalagay # x = 3 # sa equation (4) makuha namin # 5 * 3 + 3z = -42 #
o # 3z = -42-15 o 3z = -57 o z = -19 #
Paglalagay # x = 3, z = -19 # sa equation (1) makuha namin, # 4 * 3 + y + 5 * (- 19) = -40 o y = -40-12 + 95 = 43 #
Solusyon:# x = 3, y = 43, z = -19 # Ans
