Question

if 81 ( 3x+3)=243 (2x+4) , then value of x is ?

Answer 1

Step-by-step explanation:

you can do this in 2 ways they are

METHOD - 1 : Multipy by 3 an both sides i.e.,

(3)(3)x =(3)(243)

then x=81

METHOD - 2 : Divide by 3 which is on left side

3 x = 243

x = 243/ 3

x = 81

THE FINAL ANSWER IS 81

Answer 2

Answer:

x=4

Step-by-step explanation:

Here,

\frac{ {3}^{2x + 1} }{ {3}^{4} } = 243

3

4

3

2x+1

=243

now

{3}^{ 2x - 3} = {3}^{5}3

2x−3

=3

5

now,

2x - 3 = 52x−3=5

and

x = 4x=4
