Explanation Given Information: The provided equation is | x + 2 | = 5 − 2 . Formula used: Let k be a positive real number. Then, to solve the equation | a x + b | = k is same as solving the compound equations; a x + b = k or a x + b = − k Calculation: Consider the expression | x + 2 | = 5 − 2 . The solution of the above expression is same as solving the compound equations; x + 2 = 5 − 2 or x + 2 = − ( 5 − 2 ) Solve the equation x + 2 = 5 − 2 ; x + 2 = 5 − 2 x + 2 = 3 Add − 2 on both sides of the equation; x + 2 − 2 = 3 − 2 x = 1 Now, solve the equation x + 2 = − ( 5 − 2 ) ; x + 2 = − ( 5 − 2 ) x + 2 = − 3 . Add − 2 on both sides of the equation
