#3x+y-5=0#

Explanation:

The equation of a line in #color(blue)"standard form"# is.

#color(red)(bar(ul(|color(white)(2/2)color(black)(ax+by+c=0)color(white)(2/2)|)))#

#"Rearrange "y=5-3x" into this form"#

add 3x to both sides.

#y+3x=5cancel(-3x)cancel(+3x)#

#rArry+3x=5#

subtract 5 from both sides.

#y+3x-5=5-5#

#rArry+3x-5=0#

and expressing in standard form.

#3x+y-5=0larrcolor(red)" in standard form"#
