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 y varies directly as x and y = 36 when x = 4,what is the value of y when x=6?

zepelin [54]

Answer:

Step-by-step explanation:

If the two numbers vary directly, we can use a proportion to find the missing value.

36/4 = y/6

4y = 216

Divide by 4

y = 54

Check

36/4 = 54/6

216 = 216 ✅
