The solution would
be like this for this specific problem:
sin ( x - ( pi / 7 ) ) = - sqrt ( 2 ) / 2
x - ( pi / 7 ) = - pi / 4 + 2n*pi or x - ( pi / 7 ) = (5pi / 4 ) + 2n*pi
x = ( pi / 7 ) - ( pi / 4 ) + 2n*pi or x = ( 5pi / 4 ) + ( pi / 7 ) + 2n*pi
x = ( - 3pi / 28 ) + 2n*pi

An arguably quicker way without using geometric series:
Y = -2x + 4
substitute the value of x = 1 to the equation:
y = -2 · 1 + 4 = -2 + 4 = 2
