I'm not about it tho
Answer:
Your correct answer is x=6.
step by step explaination:
Subtracting a whole from a fraction
7 7 • 2
7 • 2 7= — = -----------
1 2
Add the two equivalent fractions which now have a common denominator
5x - (7 • 2) 5x - 14
= ———————————— = ——————
2 2
(5x - 14)
= —————— - 8 = 0
2
Subtracting a whole from a fraction
8 8 • 2
= 8 = — = ———
1 2
Adding up the two equivalent fractions
(5x-14) - (8 • 2) 5x - 30
= ———————————— = ———————
—— = ——————— 2 2
Pull out like factors :
= 5x - 30 = 5 • (x - 6)
5 • (x - 6)
= ————————— = 0
————————— = 0 2
5•(x-6)
= ——————— • 2 = 0 ×2
2
= 5 (x-6) = 0
= x-6 = 0
= x=6
