$\huge\text{Hey there!}$

$\large\textsf{12y + x = 48}$

$\large\text{If x = -4, then substitute for the x-value in the given equation}$

$\large\textsf{12y \underline{ - 4} = 48}$

$\large\text{ADD 4 to BOTH SIDES}$

$\large\textsf{12y - 4 + 4 = 48 + 4}$

$\large\text{CANCEL out: 4 - 4 because it gives you 0}$

$\large\text{KEEP: 48 + 4 because it helps solve for your y-value}$

$\large\textsf{48 + 4 = \boxed{\bf 52}}$

$\large\text{New EQUATION: \textsf{12y = 52}}$

$\large\text{DIVIDE 12 to BOTH SIDES}$

$\mathsf{\dfrac{12y}{12}= \dfrac{52}{12}}$

$\large\text{CANCEL out: }\mathsf{\dfrac{12}{12}}\large\text{ because it gives you 1}$

$\large\text{KEEP: }\mathsf{\dfrac{52}{12}}\large\text{ because it gives you the value of the y-value}$

$\mathsf{y = \dfrac{52}{12}}$

$\mathsf{y = \dfrac{52\div 4}{12\div4}}$

$\mathsf{52\div4=\boxed{\bf 13}}\large\checkmark$

$\mathsf{12\div4=\boxed{\bf 3}}\large\checkmark$

$\boxec{\boxed{\large\text{ }\mathsf{\bf y = \dfrac{13}{3} \ \& \ x = -4}}}\huge\checkmark$

$\large\textsf{Good luck on your assignment and enjoy your day!}$
