Answer:
i = -0.09375n-1s-1x-1
Step-by-step explanation:
Simplifying
8sin(8x) + 9 = 3
Remove parenthesis around (8x)
8ins * 8x + 9 = 3
Reorder the terms for easier multiplication:
8 * 8ins * x + 9 = 3
Multiply 8 * 8
64ins * x + 9 = 3
Multiply ins * x
64insx + 9 = 3
Reorder the terms:
9 + 64insx = 3
Solving
9 + 64insx = 3
Solving for variable 'i'.
Move all terms containing i to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + 64insx = 3 + -9
Combine like terms: 9 + -9 = 0
0 + 64insx = 3 + -9
64insx = 3 + -9
Combine like terms: 3 + -9 = -6
64insx = -6
Divide each side by '64nsx'.
