Which statement illustrates the identity property of addition?

7 + 1 = 8

7 · 1 = 7

7 · 0 = 0

7 + 0 = 7

7 + 0 = 7

Step-by-step explanation:

Identity property of addition states that when we get a same number after adding with another number, then this another number is called additive identity,

Also, the additive identity is always zero.

That is,

a + 0 = a

Where a ∈ R

Thus, the correct option which illustrates the identity property of addition is,

7 + 0 = 7

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
