100tan(x)-8=50tan(x)

Solution

100 tan (x) - 8 = 50 tan (x)

Solution

x = 0.15865 \dots + πn

Degrees

x = 9.09027 \dots^{\circ} + 18 0^{\circ} n

Solution steps

100 tan (x) - 8 = 50 tan (x)

Solve by substitution

100 tan (x) - 8 = 50 tan (x)

Let:

tan (x) = u

100 u - 8 = 50 u

100 u - 8 = 50 u : u = \frac{4}{25}

100 u - 8 = 50 u

Move

8

to the right side

100 u - 8 = 50 u

Add

8

to both sides

100 u - 8 + 8 = 50 u + 8

Simplify

100 u = 50 u + 8

100 u = 50 u + 8

Move

50 u

to the left side

100 u = 50 u + 8

Subtract

50 u

from both sides

100 u - 50 u = 50 u + 8 - 50 u

Simplify

50 u = 8

50 u = 8

Divide both sides by

50

50 u = 8

Divide both sides by

50

\frac{50 u}{50} = \frac{8}{50}

Simplify

u = \frac{4}{25}

u = \frac{4}{25}

Substitute back

u = tan (x)

tan (x) = \frac{4}{25}

tan (x) = \frac{4}{25}

tan (x) = \frac{4}{25} : x = arctan (\frac{4}{25}) + πn

tan (x) = \frac{4}{25}

Apply trig inverse properties

tan (x) = \frac{4}{25}

General solutions for

tan (x) = \frac{4}{25}

tan (x) = a \Rightarrow x = arctan (a) + πn

x = arctan (\frac{4}{25}) + πn

x = arctan (\frac{4}{25}) + πn

Combine all the solutions

x = arctan (\frac{4}{25}) + πn

Show solutions in decimal form

x = 0.15865 \dots + πn
