Question

Solve for y y+y/a=b, if a≠1

Answer 1

$\frac{y+y}{a} = b$  Multiple "a" on both sides

$\frac{y + y}{a} (a) = b(a)$

y + y = ab

2y = ab  Divide 2 on both sides

$\frac{2y}{2} =\frac{ab}{2}$

$y = \frac{ab}{2}$

Answer 2

y = $\frac{ab}{2}$

given $\frac{y+y}{a}$ = b, that is

$\frac{2y}{a}$ = b ( multiply both sides by a )

2y = ab ( divide both sides by 2 )

y = $\frac{ab}{2}$
