Discussion Topic Like fractions, rational expressions can be added, subtracted, multiplied, and divided. When dealing with two rational expressions that have different denominators, how would you find a common denominator? What effect would that have on the numerators of the expressions? Would the same idea work for simple numeric fractions? Why or why not? Given two rational expressions, how would the process you follow to multiply or divide them differ from multiplying or dividing two numeric fractions?

i can't see the picture : /

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
