What is the solution of the system of equations?

Elis [28]

Answer:

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

$\left[\begin{array}{ccc}3&2&1\\5&5&4\\3&2&3\end{array}\right]$

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

= 79 - 69

Δ = 10

$\left[\begin{array}{ccc}7&2&1\\3&5&4\\1&2&3\end{array}\right]$

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

= 119 - 79

Δx = 40

$\left[\begin{array}{ccc}3&7&1\\5&3&4\\3&1&3\end{array}\right]$

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

= 116 - 126

Δy = -10

$\left[\begin{array}{ccc}3&2&7\\5&5&3\\3&2&1\end{array}\right]$

= 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

If the product of six tenths and three tenths is subtracted from the sum of two tenths and four tenths, what

MakcuM [25]

Answer:

$-\frac{1}{200}$

Step-by-step explanation:

$\frac{6}{10}$ × $\frac{3}{10}$ - $\frac{2}{10}$ + $\frac{4}{10}$

$\frac{6}{10}$ × $\frac{3}{10}$ = $\frac{18}{100}$

$\frac{18}{100}$ - $\frac{2}{10}$ = $-\frac{1}{50}$

$-\frac{1}{50}$ + $\frac{4}{10}$ = $\frac{1}{200}$
