Answer:

$\huge\underline{ \underline{ \red{your \: \: answer}}}$

Step-by-step explanation:

$\large\boxed{ \fcolorbox{pink}{red}{x + y = yx + 4 \: or \: 0} }$

$\sf\purple{1 + 2= 21(x = 2 \: and \: y = 1 )} \\ \sf\purple{x + y = yx + 0 = 21 + 0 = 21 } \\ \sf\blue{2 + 3 = 36(x = 2 \: and \: y = 3)} \\ \sf\blue{x + y = yx + 4 = 32 + 4 = 36}\ \\ \sf\red{3 + 4 = 43(x = 2 \: and \: y = 3)} \\ \sf\red{x + y = yx + 0 = 43 + 0 = 43}\\ \sf\green{4 + 5 = 54(x = 4 \: and \: y = 5)} \\ \sf\green{x + y = yx + 0 = 54 + 4= 58}$

$\large\boxed{ \fcolorbox{red}{purple}{hope \: it \:help \: you} }$
