Answer: x = 16.75
Step-by-step explanation:
I'm not good at square roots but if you divide both sides by 2:
(2x – 9) • 2 / 2 = 49 / 2
simplify:
2x – 9 = 49/2
add 9 to both sides:
2x – 9 + 9 = 49/2 + 9
simplify:
2x = 67 / 2
divide both sides by 2:
2x ÷ 2 = 67/2 ÷ 2
simplify:
x = 67/4
Answer:
x = 16.75
Answer:
x=-2
