-9(8x — 8) = 8(-7 - 10x)

Answers

Answer:

×=1/3

Step-by-step explanation:

8x –3(5x–2)=7–10x

Distribute

8x - 15x +6 = 7-10x

Combine like terms

-7x + 6 = 7- 10x

Add 10x to each side

-7x +10x+ 6 = 7- 10x+10x

3x+6 = 7

Subtract 6 from each side

3x+6-6 =7-6

3x = 1

Divide each side by 3

3x/3 = 1/3

x = 1/3

Find what the value of x.

For the pair of supply-and-demand equations, where x represents the quantity demanded in units of 1000 and p is the unit price in dollars, find the equilibrium quantity and the equilibrium price.
p = −0.3x + 6 and p = 0.05x + 2.5
equilibrium quantity
units
equilibrium price $

Answers

9514 1404 393

Answer:

  (x, p) = (10, 3)

Step-by-step explanation:

Equating the expressions for p, we have ...

  -0.3x +6 = 0.05x +2.5

  3.5 = 0.35x . . . . . add 0.3x-2.5

  10 = x . . . . . . . . . . divide by 0.35

  p = -0.3(10) +6 = 3

The equilibrium quantity is 10 units.

The equilibrium price is $3.
