See the entire solution process below:

First, combine like terms on the right side of the equation:

#3.7 = -3x + x - 30x#

#3.7 = -3x + 1x - 30x#

#3.7 = (-3 + 1 - 30)x#

#3.7 = (-32)x#

#3.7 = -32x#

Now, divide each side of the equation by #color(red)(-32)# to solve for #x# while keeping the equation balanced:

#3.7/color(red)(-32) = (-32x)/color(red)(-32)#

#-0.115625 = (color(red)(cancel(color(black)(-32)))x)/cancel(color(red)(-32))#

#-0.115625 = x#

#x = -0.115625#
