3X+[-1 - 2] = [-13 - 2]

10 - 7 - 5 14

x = - 668/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x-1-2 = (-13-2) (10) - 7-514

3x+-1+-2=-150+-7+-514

(3x) + (-1+-2) = (-150+-7+-514) (Combine Like Terms)

3x+-3=-671

3x-3=-671

Step 2: Add 3 to both sides.

3x-3+3=-671+3

3x=-668

Step 3: Divide both sides by 3.
