Answer 2

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
