Question

7×3^(x+1)-5^(x+1)=3^(x+4)-5^(x+3)​

Answer 1

Answer:

x = 0

Step-by-step explanation:

=> 7*3 ^(x+1)- 5^(x+1) = 3^(x+4) - 5^(x+3)

=> 21^(x+1) - 5^(x+1) = 3^(x+4) - 5^(x+3)

=> (21-5)^(x+1) = 3^(x+4) - 5^(x+3)

=> (x+1) = (x+4) - (x+3)

=> x +1 = x +4 - x - 3

=> x+1 = 1

=> x = 0

I hope it will help you all
