17sin(x)+8=sin(x)

Solution

17 sin (x) + 8 = sin (x)

Solution

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

Degrees

x = 21 0^{\circ} + 36 0^{\circ} n, x = 33 0^{\circ} + 36 0^{\circ} n

Solution steps

17 sin (x) + 8 = sin (x)

Solve by substitution

17 sin (x) + 8 = sin (x)

Let:

sin (x) = u

17 u + 8 = u

17 u + 8 = u : u = - \frac{1}{2}

17 u + 8 = u

Move

8

to the right side

17 u + 8 = u

Subtract

8

from both sides

17 u + 8 - 8 = u - 8

Simplify

17 u = u - 8

17 u = u - 8

Move

u

to the left side

17 u = u - 8

Subtract

u

from both sides

17 u - u = u - 8 - u

Simplify

16 u = - 8

16 u = - 8

Divide both sides by

16

16 u = - 8

Divide both sides by

16

\frac{16 u}{16} = \frac{- 8}{16}

Simplify

\frac{16 u}{16} = \frac{- 8}{16}

Simplify

\frac{16 u}{16} : u

\frac{16 u}{16}

Divide the numbers:

\frac{16}{16} = 1

= u

Simplify

\frac{- 8}{16} : - \frac{1}{2}

\frac{- 8}{16}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{8}{16}

Cancel the common factor:

8

= - \frac{1}{2}

u = - \frac{1}{2}

u = - \frac{1}{2}

u = - \frac{1}{2}

Substitute back

u = sin (x)

sin (x) = - \frac{1}{2}

sin (x) = - \frac{1}{2}

sin (x) = - \frac{1}{2} : x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

sin (x) = - \frac{1}{2}

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

Combine all the solutions

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn
