Addition Property of Equality
WORDS Adding the same number to each side of an equation produces an equivalent equation
Algebra If x – a = b,then x – a + a = b + aor x = b + a
Addition Property of Equality
WORDS Adding the same number to each side of an equation produces an equivalent equation
Algebra If x – a = b,then x – a + a = b + aor x = b + a
X-a=b x-a+a=b+ax=b+aX-5=3 x-5+5=3+5 x=3+5
Subtraction Property of Equality
WORDS Subtracting the same number to each side of an equation produces an equivalent equation
Algebra If x + a = b,then x + a - a = b - aor x = b - a
