Heya!

Your question states: Solve for x in simplest form 15 = 1/3(x+9)

Answer: X = 36

Numerical Explanation:

1. Step by step

I. 15 = 1/3(x+9)

2. Simplify both sides of the equation:

II. 15 = 1/3x + 3

3. Flip the equation:

III. 1/3x + 3 = 15

4. Subtract 3 from both sides:

IV. 1/3 x +3 = 15

-3 -3

5. Multiply both sides by 3:

V. 3 * (1/3 x) = (3) * (12)

6. Final answer:

VI. x = 36

Answer:

x = 36

Explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS:

Remember to follow PEMDAS and the left -> right rule.

PEMDAS:

Parenthesis

Exponent (& roots)

Multiplication

Division

Addition

Subtraction

----------------

15 = 1/3(x + 9)

First, multiply 3 to both sides of the equation

(15)(3) = (1/3(x + 9))(3)

(15)(3) = x + 9

45 = x + 9

Next, to isolate the x, subtract 9 from both sides

45 (-9) = x + 9 (-9)

45 - 9 = x

36 = x

-----------

36 is your answer for x.
