How would you solve for x?

Question

X/4 + 10 = x/2
X/2 - x/3 = 600
Solve for x

Answer 1

I.  X/4 + 10 = x/2; multiply by 4 to get x + 40 =2x  and then you should be able to complete the job.

 

II. Multiply this whole equation by6 (the LCD) to get 3x - 2x = 3600 and take it from there.

This important technique is called CLEARING FRACTIONS.
