Solve 10/x + 2/x= 12. Show all of your work for full credit.

x = 1

Step-by-step explanation:

move all terms to the left

10/x+2/x-(12)=0

domain of the equation: x!=0

x∈R

multiply all the terms by the denominator

-12*x+10+2=0

add all the numbers together, and all the variables

-12x+12=0

move all terms containing x to the left, all other terms to the right

-12x=-12

x=-12/-12 - divide

none.
