Question

The value of x in the equation 3x/4=7-x is​

Answer 1

Answer:

yoo!! bro/sis ✌✌

3x/4 = 7 - x

= ( 3x + x )/4 = 7

= 4x /4 = 7

= 4x = 7 × 4

= 4x = 28

= x = 28/4

= x = 7.

Answer 2

Answer:

$\frac{3x}{4} = \frac{7 - x}{1} \\ 3x = 4(7 - x) \\ 3x = 28 - 4x \\ 3x + 4x = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4$
