Question

Using transposition method find the value of x

3/2x + 5 = 21/2 ​

Answer 1

Answer:

3/2x = 21/2 -5

3/2x = 11/2

2x = 11/2 multiply 3

2x=33/2

x=33/2/2

x= 33/4

hope it helps....

Answer 2

$\frac{3}{2x} + 5 = \frac{21}{2} \\ \frac{3 + 5(2x)}{2x} = \frac{21}{2} \\ \frac{3 + 10x}{2x} = \frac{21}{2} \\ 2(3 + 10x) = 21(2x) \\ 6 + 20x = 42x \\ 6 = 42x - 20x \\ 6 = 22x \\ x = \frac{6}{22} \\ x = > \frac{3}{11}$
