Question

please help!!! What is the solution to the equation
2^1 - 2x = 3 ?

Answer 1

Well
x^1=x

So that means 2^1=2

Answer 2

2^1=2
so
2-2x=3
can you solve this?

Answer 3

@shannondidier follow off of what zz did

Answer 4

i got -2, but my answer choices are x ≈ -0.292
x ≈ -0.185
x ≈ 0.185
x ≈ 0.292

Answer 5

Is the x an exponent too?

Answer 6

the 1-2x is an exponent

Answer 7

Answer 8

I believe the original problem is \[2^{1-2x}=3\]

Answer 9

it is

Answer 10

2^(1-2x) = 3
1-2x=log_2(3)
1-log_2(3)=2x
x=(1-log_2(3))/2

Answer 11

about -0.292

Answer 12

thank you so much, i understand now! :)

Answer 13

good deal
