Question

:)
It's known that x + y = 10. Is it true to say x + y + z = 10 + 2? Explain using suitable
axioms.​

Answer 1

Answer:

True

Step-by-step explanation:

x+y=10

• Now come to second one

$\longrightarrow\sf x+y+z=10+2$

• Substitute the value of first equation

$\longrightarrow\sf 10+z=10+2$

$\longrightarrow\sf z=2$

Answer 2

Answer:

Here z has been added to two quantities which are equal to each other.

So, by Euclid's second axiom, which states that

if equals are added to equals the wholes are equal,

x+y+z=10+z is true.
