Question 70760
{{{92=R-.08R}}}
.
Notice that 1R (or just R) and -0.08R are common terms and can be subtracted directly.
When you do this subtraction, the result is 0.92R.  So now your equation is:
.
{{{92 = 0.92R}}}
. 
You can solve for R by dividing both sides by 0.92.  The equation becomes:
.
{{{92/0.92 = 0.92*R/0.92}}}
.
Performing the division results in:
.
{{{100 = R}}}
.
That's the answer.  Another approach you could take to get the same result is to factor R
out of the Right side. If you do this factoring, you get:
.
{{{92 = R*(1 - 0.08)}}}
.
The terms in the parentheses can be combined by subtraction to give you 0.92. The equation
then becomes:
.
{{{92 = R*0.92}}}
.
This is the same result as we had before.  Just divide both sides by 0.92 and you end
up with R = 100 again.
.
I hope this helps you with this problem.
