Part 1: Explain how you calculate the restricted value(s) of x for the equation 3/x+2 +1/2x= 4/x+2
you can not have a '0' in the denominator of any fraction, so look into the equation and see which numbers will result in a '0' in a denominator
Explain which method (cross-multiplication or LCD) you would use to solve the equation and why. i dont undestand either method
I would use LCD. it is the easiest here. look at what the denominators are. for the ones that are 'x + 2', multiply the fraction by 2x/2x, so it shares a common denominator with the middle fraction. then on the middle fraction, multiply it by x+2/x+2 so it shares a denominator with the other two fractions. now they all have a denominator of 2x(x+2). now you can add/subtract the numerators. that should help you finish the problem
thank you
