Answer to Problem 9E

The error in solving the equation is in first step where the sum of x and −4x isdetermined as 3x instead of −3x .

The correct solution of the equation is x=−3

Explanation of Solution

Given information:

The equation is 4x+7=x−2 .

Calculation:

the solution of the equation provided in the question is:

  4x+7=x−24x+7−4x=x−2−4x7=3x−27+2=3x−2+29=3x3=x

From, the above solution, it is observed that the error occurred in first step where the sum of x and −4x is determined as 3x instead of −3x .

The solution is obtained as:

  4x+7=x−2                                           write the original equation4x−x+7=x−x−2                                subtract x from both sides3x+7=0−2                                            simplify3x+7−7=−2−7                                    subtract 7 from both sides3x =−9                                                    simplify3x3=−93                                                   divide each by 3 x=−3                                                       simplify

The error in solving the equation is in first step where the sum of x and −4x isdetermined as 3x instead of −3x .

The correct solution of the equation is x=−3
