a = -5

Step-by-step explanation:

Given

$- 6 + \sqrt{9 - 8a} = 1$

Required

Solve for a

$- 6 + \sqrt{9 - 8a} = 1$

Add 6 to both sides

$6- 6 + \sqrt{9 - 8a} = 1+6$

$\sqrt{9 - 8a} = 7$

Square both sides

$( \sqrt{9 - 8a})^2 = 7^2$

9 - 8a = 49

Subtract 9 from both sides

9-9 - 8a = 49-9

- 8a = 40

Make a the subject

$a = -\frac{40}{8}$

a = -5
