0=4sin(12x+90)-2

Solution for 0=4sin(12x+90)-2 equation:

Simplifying
0 = 4sin(12x + 90) + -2

Reorder the terms:
0 = 4ins(90 + 12x) + -2
0 = (90 * 4ins + 12x * 4ins) + -2
0 = (360ins + 48insx) + -2

Reorder the terms:
0 = -2 + 360ins + 48insx

Solving
0 = -2 + 360ins + 48insx

Solving for variable 'i'.

Move all terms containing i to the left, all other terms to the right.

Add '-360ins' to each side of the equation.
0 + -360ins = -2 + 360ins + -360ins + 48insx
Remove the zero:
-360ins = -2 + 360ins + -360ins + 48insx

Combine like terms: 360ins + -360ins = 0
-360ins = -2 + 0 + 48insx
-360ins = -2 + 48insx

Add '-48insx' to each side of the equation.
-360ins + -48insx = -2 + 48insx + -48insx

Combine like terms: 48insx + -48insx = 0
-360ins + -48insx = -2 + 0
-360ins + -48insx = -2

Reorder the terms:
2 + -360ins + -48insx = -2 + 2

Combine like terms: -2 + 2 = 0
2 + -360ins + -48insx = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(1 + -180ins + -24insx) = 0

Ignore the factor 2.
Subproblem 1
Set the factor '(1 + -180ins + -24insx)' equal to zero and attempt to solve:

Simplifying
1 + -180ins + -24insx = 0

Solving
1 + -180ins + -24insx = 0

Move all terms containing i to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -180ins + -1 + -24insx = 0 + -1

Reorder the terms:
1 + -1 + -180ins + -24insx = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -180ins + -24insx = 0 + -1
-180ins + -24insx = 0 + -1

Combine like terms: 0 + -1 = -1
-180ins + -24insx = -1
