Question

If 7/5 + X = 7/3 then the value of X is A. 13/15 B. 11/15 C. 14/15 D. 11/14

Answer 1

Answer:

8 ∙ 2x = 5(y+8).

or, 8 ∙ 2x = 5(-8+8).

or, 2x = 50.

or, 2x = 1 [anything to the power 0 is 1 then, 50 = 1].

Taking log on both sides,

log 2x = log 1.

or, x log 2 = 0 [since log 1 = 0].

or, x = 0/log 2 [dividing log 2 on both sides].

Therefore, x = 0.

Answer 2

Answer:

C. 14/15

Step-by-step explanation:

$\frac{7}{5}+X=\frac{7}{3}\\\\X = \frac{7}{3} - \frac{7}{5}\\\\X = \frac{35}{15}-\frac{21}{15}\\\\X = \frac{35-21}{15}\\\\X = \frac{14}{15}$

Hope it helps you mate..
