Isolate the s. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
Subtract 19 from both sides
7 (-19) = 4s + 19 (-19)
7 - 19 = 4s
-12 = 4s
Isolate the s. Divide 4 from both sides
-12/4 = 4s/4
s = -12/4
s = -3
-3 is your answer for s

Answer:
x ≈ 0.1459
Step-by-step explanation:
Since you only want a small positive solution, you can use the arcsine function to find it.
6sin(5x) = 4
sin(5x) = 4/6 = 2/3
5x = arcsin(2/3)
x = arcsin(2/3)/5
x ≈ 0.1459

A graphing calculator can find the solution easily. It is often easiest to rewrite the equation so you're looking for a solution that makes the value zero. Here, subtracting 4 from both sides does that.
