Answer:

x = 5

Step-by-step explanation:

Step 1: Subtract 2x from both sides.

4x−3−2x=2x+7−2x

Step 2: Add 3 to both sides.

2x−3+3=7+3

Step 3: Divide both sides by 2.

2x/2 = 10/2

x=5

Answer:

The answer is

$p = \frac{ - 3}{1000} n + 97$

Step-by-step explanation:

We have the points (2000,91) and (5000,82)

Then

$m = \frac{91 - 82}{2000 - 5000} = \frac{ - 3}{1000} \\ to \: find \: the \: b \\ 91 = \frac{ - 3}{1000} \times 2000 + b \\ b = 97 \\ then \: the \: equation \: is \: \\ p = \frac{ - 3}{1000} n + 97$
