DIRECTIONS : Using Graphical Method

  • -x + y = 4
  • -x + y = 5

===========================================

ANSWER : For #1. -x + y = 4

  • [tex]\red{\boxed{ \red{\boxed{ \rm x=y-4 \: or \: y=x+4 }}} }[/tex]

===========================================

SOLUTION 1: solve for x

  • [tex]\rm{ -x+y=4 }[/tex]
  • [tex]\rm{ -x=4-y }[/tex]
  • [tex]\rm{ \frac{-x}{-1}=\frac{4-y}{-1} }[/tex]
  • [tex]\rm{ x=\frac{4-y}{-1} }[/tex]
  • [tex]\rm\red{\underline{ \: x=y-4 }}[/tex]

===========================================

SOLUTION 2: solve for y

  • [tex]\rm{ -x+y=4 }[/tex], we'll just add x to both sides so the answer is [tex]\rm\red{\underline{ \: y=4+x }}[/tex]

===========================================

ANSWER : For #2. -x + y = 5

  • [tex]\red{\boxed{ \red{\boxed{ \rm x=y-5\: or\: y=x+5 }}} }[/tex]

===========================================

SOLUTION 1: solve for x

  • [tex]\rm{ -x+y=5 }[/tex]
  • [tex]\rm{ -x=5-y }[/tex]
  • [tex]\rm{ \frac{-x}{-1}=\frac{5-y}{-1} }[/tex]
  • [tex]\rm{ x=\frac{5-y}{-1} }[/tex]
  • [tex]\rm\red{\underline{ \: x=y-5 }}[/tex]

===========================================

SOLUTION 2: solve for y

  • [tex]\rm{ -x+y=5 }[/tex], like what we did earlier, we'll just add x to both sides so the possible answer is [tex]\rm\red{\underline{ \: y=5+x }}[/tex]
