Question

Solve for x

Answer 1

can someone please help explain how you got that answer?

Answer 2

get rid of x in the denominator by:
x(3/x) = x(x/32)

This gives you 3=(x^2)/32

then you get rid of the 32 in the denominator to isolate the x which gives you:
32(3) = 32((x^2)/32) ---- (You see how the 32 cancels out on the right?)

now you are left with 32(3) = x^2 ====> 96 = x^2

x = (+ or -)sqrt(96)

Answer 3

your main objective is to get x onto one side, so that's where you start when given a problem like this. and if you have a fraction on either side you multiply the fraction by its denominator on both sides of the equal sign to maintain algebraic sense..

ex. 1/x = 2.. x =?
(x)(1/x) = 2(x) =====> 1 = 2x ====> 1(1/2) = 2x(1/2) *the two cancels out* andyou are left with ===> 1/2 = x.

Answer 4

ok.. um i am rereading it and its kinda hard to understand, is there any other resource you can give me to figure out problem like these?

Answer 6

sorry, it's probably because of the way it's written. try http://tutorial.math.lamar.edu/Classes/Alg/SolveLinearEqns.aspx

Answer 7

you're in algebra, correct?
