Answer:

x = 4

Explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 3x/4 = (2x + 7)/5

Then the value of x will be,

→ 3x/4 = (2x + 7)/5

→ 5(3x) = 4(2x + 7)

→ 15x = 4(2x) + 4(7)

→ 15x = 8x + 28

→ 15x - 8x = 28

→ 7x = 28

→ x = 28 ÷ 7

→ [ x = 4 ]

Hence, the value of x is 4.
