Question

Help please asap I NEED THE WORKING TOO!!!!!!!​

Answer 1

9 / 7 = a

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

Answer 2

9/7 =a

Explanation:

9 / -a + 15 = 8

Subtract 15 from each side

9 / -a + 15 -15 = 8-15

9 / -a = -7

Multiply each side by -a

9/-a * -a = -7 * -a

9 =7a

Divide each side by 7

9/7 = 7a/7

9/7 =a
