Best ResponseYou've already chosen the best response.0wait theres an ln in it before the 2x3

Best ResponseYou've already chosen the best response.0Use math properties to isolate x. Start by adding 10 to both sides, then divide by 100 on both sides etc.

Best ResponseYou've already chosen the best response.0okay, then what should i do with the ln?

Best ResponseYou've already chosen the best response.0the ln part confuses me, im not too good with it

Best ResponseYou've already chosen the best response.0ok, so first im pretty sure that you have to distribute the 100 to the 2 and 3 then you should put the 300 and the 10 together

Best ResponseYou've already chosen the best response.0making 310, with this you should add it to the other side of the = sign

Best ResponseYou've already chosen the best response.0e is the inverse of ln. So if both sides are e raised to a power. You will get e^(ln(2x3)=e^1.12

Best ResponseYou've already chosen the best response.0but how do i solve for the x?

Best ResponseYou've already chosen the best response.0100(2x3)10=102 200x30010=102 200x310=102 200x=412 because you added the 210 the the 102 then you should divide 400 by 200 that should leave you with x=2.06

Best ResponseYou've already chosen the best response.0you left out the ln (natural logarithm)

Best ResponseYou've already chosen the best response.0So e^(ln) is 1. So the left side goes to 2x3. So you should get 2x3=e^(1.12)

Best ResponseYou've already chosen the best response.0ok, so i set 2x3=1.12. then i added 3 to 1.12 and got 2x=4.12.

Best ResponseYou've already chosen the best response.0No. You left out the e. E is a function in itself just like ln. So you can use a calculator to find the value of e^1.12. Then you can continue with your process.

Best ResponseYou've already chosen the best response.0ok, so i got 3.065 for e^1.12. then i added 3 to that. i got 2x=6.065. then i divided by two and got x=3.033. sound right?

Best ResponseYou've already chosen the best response.0You can always check by plugging your value of x back into the equation and seeing if it's equal.
