−2∣5w−7∣+9=−7
What is the 2 answers for this question
1 answer:
The two possible answers are w = 3 and w = -1/5 These answers can be obtained through solving to the absolute value symbols. <span>−2∣5w−7∣+9=−7 ---> subtract 9 from both sides </span><span>−2∣5w−7∣= -16 ---> divide both sides by -2 </span>∣5w−7∣= 8 Now, because of the absolute value symbols, set the inside equal to 8 and -8 for the two answers. 5w - 7 = 8 5w = 15 w = 3 AND 5w - 7 = -8 5w = -1 w = -1/5
