First, isolate the #p# term (#3.2p#) on the right side of the equation while keeping the equation balanced:
#-4.52 - color(red)(1.48) = 3.2p + 1.48 - color(red)(1.48)#
#-6 = 3.2p + color(red)(0)#
#-6 = 3.2p#
Now, solve for #p# and keep the equation balanced by dividing each side of the equation by #3.2#:
#(-6)/color(red)(3.2) = (3.2p)/color(red)(3.2)#
#-1.875 = (color(red)(cancel(color(black)(3.2)))p)/color(red)(cancel(color(black)(3.2)))#
#-1.875 = p#
or
#p = -1.875#
