What is the solution of the system of equations?
3 x + 2 y + z = 7
5 x + 5 y + 4 z = 3
3 x + 2 y + 3 z = 1

The answer to your question is:

x = 4

y = -1

z = -3

Step-by-step explanation:

                                  3 x + 2 y + z = 7

                                  5 x + 5 y + 4 z = 3

                                  3 x + 2 y + 3 z = 1

= 45 + 10 + 24 - (30 + 24 + 15)

= 79 - 69

Δ = 10

= 105 + 6 + 8 - (18 + 56 + 5)

= 119 - 79

Δx = 40

= 27 + 5 + 84 - ( 105 + 12 + 9)

= 116 - 126

Δy = -10

= 15 + 70 + 18 - (10 + 18 + 105)

= 103 - 133

= -30

Δz = -30

x = Δx /Δ = 40/10 = 4

y = Δy/Δ = -10/10 = -1

z = Δz/Δ = -30/10 = -3
