Answer:

no solution

Step-by-step explanation:

6x - 3y = 7 → (1)

- 2x + y = - 8 → (2)

multiplying (2) by 3 and adding to (1) eliminates the variables

- 6x + 3y = - 24 → (3)

add (1) and (3) term by term

0 + 0 = - 17

0 = - 17 ← false statement

This indicates the system has no solution

Solving for L, we have ...

L = V/(WD) = (1700 ft³)/((17 ft)(4 ft)) = 100/4 ft = 25 ft

X=4-k over 6, what is k

Alla [95]

Answer:

Step-by-step explanation:

$x =\frac{4-k}{6}$

Cross Multiply

$x \times 6 = (4-k)\times 1\\\\6x = 4-k$

Isolate k

$6x -4 =-k$

Divide through by -1

$\frac{6x}{-1} -\frac{-4}{-1} = \frac{-k}{-1}\\ \\-6x+4 =k\\\\k =-6x+4$
