    Answer:y would equal 31 after addding 21 to both sides which eliminates x on one side and make 31 on the other

    \large\text{Hey there!}

    \large\text{x + y = 10}

    \large\text{If \bf{\underline{x = -21}}}\large\text{ the replace x in the equation with -21}

    \large\text{New equation: -21 + y = 10}\\\\\large\text{First: \bf{SIMPLIFY}}\large\text{ both sides of your equation}\\\large\text{y - 21 = 10}\\\\\large\text{Second: \bf{ADD}}\large\text{ by 21 on your sides}\\\large\text{y - 21 + 21 = 10 + 21}\\\\\large\text{Cancel out:  -21 + 21 because it equals 0 and it DOESN'T gives you y }\\\\\large\text{Keep: 10 + 21 because it gives you the value of y}\\\\\\\large\text{10 + 21 = 31}\\\\\boxed{\boxed{\large\text{Answer: \boxed{\huge\text{y = 31}}}}}\huge\checkmark
