12 - 3x = 6 help please

x = 2

Step-by-step explanation:

Solve for x:

12 - 3 x = 6

Hint: | Isolate terms with x to the left hand side.

Subtract 12 from both sides:

(12 - 12) - 3 x = 6 - 12

Hint: | Look for the difference of two identical terms.

12 - 12 = 0:

-3 x = 6 - 12

Hint: | Evaluate 6 - 12.

6 - 12 = -6:

-3 x = -6

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 x = -6 by -3:

(-3 x)/(-3) = (-6)/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

x = (-6)/(-3)

Hint: | Reduce (-6)/(-3) to lowest terms. Start by finding the GCD of -6 and -3.

The gcd of -6 and -3 is -3, so (-6)/(-3) = (-3×2)/(-3×1) = (-3)/(-3)×2 = 2:

 x = 2

the answer is 15% decrease
