#y=4x+23#

After seeing Jim's solution I did a quick search and found this is the 'slope intercept form'

As per Jim's format we have

#4x-y=-23#

This is a variant on the straight line equation of standardised form:
#y=mx+c#

Multiply everything inside the brackets by 4

#y-7=4x+16#

Add #color(red)(7)# to both sides

#color(green)(y-7color(red)(+7)=4x+16color(red)(+7))#

but #-7+7=0#

#y+0=4x+23#

#y=4x+23#
