Multiply both sides by 3

Simplify the numerators

Multiply both sides by 6

Simplify the numerator

Multiply both sides by x
12x - 18 = 15x Subtract 12x from both sides
-18 = 3x Divide both sides by 3
-6 = x Switch the sides to make it easier to read
x = -6
Check your answer by plugging -6 in for the x in the original problem:

Plug in -6 for x

Change

to

so all denominators are the same

Change

to

for easier work

Subtract the numerators (4 - (-1) )

=

So,
x = -6 .
Multiply the two values together. 7.62 x 1.23 = 9.3726
10^2 x 10^4 = 10^6.
9.3726 x 10^6 is the answer in Scientific Notation.
Answer:
n = 6
Step-by-step explanation:
2 = 
multiply both sides by 3
=> n = 6
We have the following:

solving for x

The solution of x is equal to 28, therefore 12 is not a solution of the equation
