Answer 1

Both the expressions have the value of 42

Step-by-step explanation:

Given:

expressions are-

35-(-7)

35+7

To find:

Values of both the expressions and compare

Solution:

First, we solve both the expressions

Looking at 35-(-7)

We know that two negatives result in a positive which is an addition

∴  35-(-7) = 35 +7............the sign changes as we open the bracket

= 42

∴  35-(-7) = 42

Next, 35+7

This is a simple expression of adding two terms 35 & 7

We get 42

∴ 35+7 = 42

Hence, we compare and notice that both the expressions 35-(-7) & 35+7 have equal and same values.

Answer 2

Given the first expression $35-(-7)$

We need to simplify it

Now,

$35-(-7)\\=35+7 \ \ \ [\because (-) \times (-) = (+)]\\=42$

Given the second expression is $35+7$

Now we solve this expression

$35+7\\=42$

We compare both the result and we get

$35-(-7)=35+7$

Therefore, both expressions are equal.
