d) none of these
plzz tell me the right answer I'll mark it brainlist promise ​

Answer 1

Answer:

2a+3/7=4a/5

2a-4a/5=3/7

(10a-4a) /5=3/7

6a=(3/7)*5

6a=15/7

a=15/7*6

a=5/12

Step-by-step explanation:

none of these option d is correct answer

Answer 2

$2a + \frac{3}{7} = \frac{4a}{5}$

$\frac{(2a \times 7) + 3}{7} = \frac{4a}{5}$

$\frac{14a + 3}{7} = \frac{4a}{5}$

$28a = 70a + 15$

$70a - 28a = 15$

$42a = 15$

$a = \frac{42}{15} = 2.54694$
