|2x-5|=9 what is the positive and negative answer
1 answer:
x = 7 or x = -2
|2x − 5| = 9 and |2x − 5| = -9
Add 5 to both sides
2x - 5 + 5 = 9 + 5
Simplify
2x = 14
Divide both sides by 2
2x / 2 = 14 / 2
<u>x = 7</u>
Add 5 to both sides
2x - 5 + 5 = -9 + 5
Simplify
2x = -4
Divide both sides by 2
2x / 2 = -4 / 2
<u>x = -2</u>
