9=14(2/x)
We move all terms to the left:
9-(14(2/x))=0
Domain of the equation: x))!=0We add all the numbers together, and all the variables
x!=0/1
x!=0
x∈R
-(14(+2/x))+9=0
We multiply all the terms by the denominator
-(14(+2+9*x))=0
We calculate terms in parentheses: -(14(+2+9*x)), so:We get rid of parentheses
14(+2+9*x)
We add all the numbers together, and all the variables
14(9x+2)
We multiply parentheses
126x+28
Back to the equation:
-(126x+28)
-126x-28=0
We move all terms containing x to the left, all other terms to the right
-126x=28
x=28/-126
x=-2/9
