Answer:
a = 9 / 7
step by step explanation:
9 / - a + 15 = 8
Determined the defined range
9 / ( - a ) + 15 = 8 , a ≠ 0
subtract 15 from each side
9 / - a + 15 - 15 = 8 - 15
calculate the difference
9 / - a = - 7
multiply both side of equation by - a
9 / - a × - a = - 7 × - a
9 = 7 a
divide each side by of equation by -7
9 / 7 = 7 a / 7
9 / 7 = a
swap the side of equation . ( optional )
a = 9 / 7
