Question

Solve. 7^x – 5 = 7^4x + 7

Answer 1

subtract 4x from both sides
7x-5-4x = 4x-4x+7
3x - 5 = 7
now add 5 to both sides
3x - 5 + 5 = 7 + 5
3x= 12
now divide 3 on both sides
x=4.

Answer 2

2/3?

Answer 3

are you not solving for x?

Answer 4

the answer is x=4

Answer 5

7x-5-2401x=7

Answer 6

no its 2/3 I was right

Answer 7

yeah well

Answer 8

It would be better to write this correctly
Solve. 7^x – 5 = 7^4x + 7

should be written as 7^(x-5) = 7^(4x+7)
the parentheses are important here, otherwise it looks like a much harder problem, and it confuses people.

btw, 2/3 is the right answer.
