Solve for xx:\newline5+3sinx=75+3\sin x=7

Full solution

Q. Solve for xx:\newline5+3sinx=75+3\sin x=7
  1. Isolate sine term: Isolate the sine term on one side of the equation.\newline5+3sinx=75 + 3\sin x = 7\newline3sinx=753\sin x = 7 - 5 (subtracting 55 from both sides)
  2. Simplify right side: Simplify the right side of the equation. 3sinx=23\sin x = 2
  3. Divide by 33: Divide both sides by 33 to solve for sinx\sin x.\newlinesinx=23\sin x = \frac{2}{3}
  4. Find xx value: Find the value of xx by taking the inverse sine (arcsin) of 23\frac{2}{3}.\newlinex=arcsin(23)x = \arcsin\left(\frac{2}{3}\right)
