Simplifying Sin(7x) + -1sin(x) = 0 Remove parenthesis around (7x) inS * 7x + -1sin(x) = 0 Reorder the terms for easier multiplication: 7inS * x + -1sin(x) = 0 Multiply inS * x 7inxS + -1sin(x) = 0 Multiply ins * x 7inxS + -1insx = 0 Reorder the terms: -1insx + 7inxS = 0 Solving -1insx + 7inxS = 0 Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Factor out the Greatest Common Factor (GCF), 'inx'. inx(-1s + 7S) = 0Subproblem 1
Set the factor 'inx' equal to zero and attempt to solve: Simplifying inx = 0 Solving inx = 0 Move all terms containing i to the left, all other terms to the right. Simplifying inx = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(-1s + 7S)' equal to zero and attempt to solve: Simplifying -1s + 7S = 0 Reorder the terms: 7S + -1s = 0 Solving 7S + -1s = 0 Move all terms containing i to the left, all other terms to the right. Add '-7S' to each side of the equation. 7S + -7S + -1s = 0 + -7S Combine like terms: 7S + -7S = 0 0 + -1s = 0 + -7S -1s = 0 + -7S Remove the zero: -1s = -7S Add 's' to each side of the equation. -1s + s = -7S + s Combine like terms: -1s + s = 0 0 = -7S + s Simplifying 0 = -7S + s The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
