I NEED A REFRESHER COURSE IN BASIC ALGEBRA.  STEPS TO SOLVE AN EQUATION SUCH AS

4/X  = 2/3 + 6.  I KNOW THE ANSWER IS 6 BUT DO NOT KNOW THE STEPS TO GET THAT ANSWER.

Hey, I'm not sure if you meant for me to solve 4/x = 2/3, or to solve 4/x = 2/3 + 6.  I solved both just in case.

4/x = 2/3  Need to get x on a side by itself.  For this proportion, cross-multiply.

x*2 = 4*3   Now simplify and multiply 4 by 3.

x*2 = 12     Divide 2 over to the other side of the equation.

x = 6

Incase you wanted the solution for this equation:

4/x = 2/3 + 6

Need to get x on a side by itself.  Easiest to setup a proportion, then cross-multiply.  First change 6 into a fraction with a common denominator as 2/3.  So 6 is now written as 18/3

4/x = 2/3 + 18/3  Now add the two fractions on the right hand side of the equation.

4/x = 20/3   Cross multiply next.

20*x = 4*3

x = 12/20

x = 3/5
