What is the solution to the equation 3 1 – 2x = 2 ? x ≈ –0.292 x ≈ –0.185 x ≈ 0.185 x ≈ 0.292
31-2=2x...now solve for x
is it 3(1-2x)=2
Is the equation \[\Large 3^{1-2x} = 2\] ???
You must have written the problem down wrong.
no
can you rewrite your equation?
What is the solution to the equation 3 ^1 – 2x = 2 ?
That still wouldn't give any of the possible answers you have listed.
3-2x=2......3-2=2x....now you can solve for x
Oh, I see now.
Just one sec.
You have to use logarithms to solve this problem.
everything is correct but the final answer is positive
Whoops, Jim is right.
\[\Large 3^{1-2x} = 2\] \[\Large 1-2x = \log_{3}(2)\] \[\Large -2x = \log_{3}(2) - 1\] \[\Large x = -\frac{\log_{3}(2) - 1}{2}\] \[\Large x \approx 0.18453512321428\] \[\Large x \approx 0.185\]
How did you get that Jim I have no idea how to
which step is throwing you off?
Everything lol
Step 1 ... Start with the original equation Step 2 ... Convert to logarithmic form Step 3 ... Subtract 1 from both sides. Step 4 ... Divide both sides by -2. Step 5 ... Use a calculator to approximate the right side Note: you type in "-(log(2)/log(3)-1)/(2)" without quotes Step 6 ... Round to 3 decimal places
Let me know if that helps
