Question

to solve x+11=23,Jasmine subtracted 11 from both sides of the equation. which property justifies this step?

Answer 1

The best answer is C.

The subtraction quality pf equality states that when you subtract a the same number from both sides of an equation, the result is still equal.

Answer 2

Answer:

C. Subtraction property of equality.

Step-by-step explanation:

By Commutative property of addition,

a + b = b + a Where a and b are any numbers,

By Addition property of equality,

a = b ⇒ a + c = b + c Where s, b and c are any number,

By Subtraction property of equality,

a = b ⇒ a - c = b - c Where s, b and c are any number,

By Associative property of addition,

a + ( b + c ) = (a + b ) + c,

Here, the given equation,

x + 11 = 23,

Her step is x + 11 - 11 = 23 - 11

Hence, by the above explanation it is clear that,

Her step justified Subtraction property of equality.

Option C is correct.
