4x - 3 = 6x + 9 linear equations

1 answer:

8 0

First, we have to get the variable to one side of the equation, which can be done with simple subtraction.

4x -3 (-6x) = 6x + 9 (-6x)
-2x -3 = 9

now just solve as a regular equation:
-2x - 3 = 9
-2x = 12
x = -6

so, x is equal to -6

Lana71 [14]

Answer:

9.09%

Step-by-step explanation:

To find percent decrease you have to use this equation:

$Percent Decrease = \frac{Initial -New}{Initial} x 100$

Initial = 49.5

New = 45

Plug in and solve:

$PD = \frac{49.5-45}{49.5} x 100\\\\PD = \frac{4.5}{49.5} x 100 \\\\PD = 0.0909 x 100\\\\PD = 9.09$

The percent decrease is 9.09%
