Linear Inequalities Unit Test 17 of 1817 of 18 Items Question Identify the error: −3|x−4|−4=3 Step 1 −3|x−4|=7 Step 2 |x−4|=−73 Step 3 x=53 or x=193(1 point) Responses There is an error in step 3. The absolute value is never negative, so there is no solution. There is an error in step 3. The absolute value is never negative, so there is no solution. There is an error in step 2. Dividing both sides of the equation −3|x−4|=7 by −3 gets |x−4|=−37. There is an error in step 2. Dividing both sides of the equation negative 3 Start Absolute Value x minus 4 End Absolute Value equals 7 by negative 3 gets Start Absolute Value x minus 4 End Absolute Value equals negative 3 sevenths . There is an error in step 3. The solutions should be x=−53 or x=−193. There is an error in step 3. The solutions should be x equals negative 5 thirds or x equals negative Start Fraction 19 over 3 End Fraction . There is no error. There is no error.
