Answer:
38.5 = x
Step-by-step explanation:
9/ (x+2) = 2/9
Using cross products
9*9= 2(x+2)
Distribute
81 = 2x+4
Subtract 4 from each side
81-4 = 2x+4-4
77= 2x
Divide each side by 2
77/2 = 2x/2
x= -16
first subtract 2 from both sides: 9/x= 2/9 - 2
then turn 2 into a fraction with a denominator of 9: 9/x= 2/9 - 18/9
then divide both side of the equation by 9: x= 2- 18
simplify: x= -16
