Question

Solve for y
r/3-2/y=5/5

Answer 1

`\large\boxed{y=(6)/(r-3)}`

Explanation:

`(5)/(5)=1\\\\(r)/(3)-(2)/(y)=1\qquad\text{multiply both sides by 3}\\\\r-(6)/(y)=3\qquad\text{subtract}\ r\ \text{from both sides}\\\\-(6)/(y)=3-r\qquad\text{change the signs}\\\\(6)/(y)=r-3\\\\(6)/(y)=(r-3)/(1)\qquad\text{cross multiply}\\\\y(r-3)=(6)(1)\qquad\text{divide both sides by}\ (r-3)\\eq0\\\\y=(6)/(r-3)`
