Answer:

Solving the equation : y+\frac{y}{a}=b\:if\:a\neq\: -1  for y we get \mathbf{y= \frac{ab}{a+1},\:if\:a\neq -1}

Step-by-step explanation:

We need to solve for y the equation: y+\frac{y}{a}=b\:if\:a\neq\: -1

We need to find value of y

Solving:

y+\frac{y}{a}=b

Taking LCM of a, 1 we get a

\frac{a*y+y}{a}=b\\\frac{ay+y}{a}=b

Multiply both sides by a, a will be cancelled on left side

a(\frac{ay+y}{a})=ab\\ay+y=ab

Taking y common from left side:

y(a+1)=ab

Divide both sides by a+1

\frac{y(a+1)}{a+1}=\frac{ab}{a+1}\\y= \frac{ab}{a+1},\:if\:a\neq -1

So, Solving the equation : y+\frac{y}{a}=b\:if\:a\neq\: -1  for y we get \mathbf{y= \frac{ab}{a+1},\:if\:a\neq -1}
