Answer 1

Answer:

please mark me as the brainliest answer

Step-by-step explanation:

Consider the given equations,

a+b=7 ……….. (1)

a−b=3 …………. (2)

From equation (2),

a=3+b

Put, the value of a in equation (1), we get

b+3+b=7

2b=4

b=2

Now, put the value of b in equation (2), we get

a−2=3

a=5

Hence, a=5,b=2. This is the answer.

Answer 2

Explanation:

Given:

$(a-b)^3$

By solving this equation in one word ,

So we get ,

$a^3 -b^{3} -3ab(a-b)$
