Answer:
y = 5/18
Step-by-step explanation:
50/90-y=5/18
Lets simplify our fractions
50/90 = 5/9 (divide top and bottom by 10)
5/9 - y = 5/18
Subtract 5/9 from each side
5/9 -5/9 -y = 5/18 - 5/9
-y = 5/18 - 5/9
We need to get a common denominator of 18
-y = 5/18 - 5/9 *2/2
-y = 5/18 -10/18
-y = -5/18
Multiply each side by -1
-1*-y = -5/18 * -1
y = 5/18
