Step-by-step explanation:

V > - 2

Solve the equation.<br> 5/6x - 4 = -2
SVEN [57.7K]

Answer:

x = 12/5

General Formulas and Concepts:

Order of Operations: BPEMDAS

Step-by-step explanation:

<u>Step 1: Define equation</u>

5/6x - 4 = -2

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Add 4 to both sides:                         5/6x = 2
  2. Divide both sides by 5/6:                 x = 12/5

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    5/6(12/5) - 4 = -2
  2. Multiply:                        2 - 4 = -2
  3. Subtract:                       -2 = -2
