Question

1. -(72-y)+(-y+16);2(- 26+x+y) - (x-y-26);СРОЧНО ​

Answer 1

Ответ:

1. -72+у-у+16=-56

2. -26+х+у-х+у+26 = 2у

Answer 2

1. Let's simplify the expression -(72 - y) + (-y + 16):

Step 1: Distribute the negative sign in front of the parentheses: -(72 - y) = -72 + y

Step 2: Distribute the negative sign inside the second set of parentheses: (-y + 16) = -y + 16

Now we can combine like terms: (-72 + y) + (-y + 16) = -72 - y - y + 16

Combining the y terms and the constant terms, we get: -72 - 2y + 16

Simplifying further, we have: -56 - 2y

Therefore, -(72 - y) + (-y + 16) simplifies to -56 - 2y.

2. Now let's simplify the expression 2(-26 + x + y) - (x - y - 26):

Step 1: Distribute the 2 to the terms inside the parentheses: 2(-26 + x + y) = -52 + 2x + 2y

Step 2: Distribute the negative sign in front of the second set of parentheses: -(x - y - 26) = -x + y + 26

Now we can combine like terms: (-52 + 2x + 2y) - (-x + y + 26) = -52 + 2x + 2y + x - y - 26

Combining the x terms, the y terms, and the constant terms, we get: 2x - y - 78

Therefore, 2(-26 + x + y) - (x - y - 26) simplifies to 2x - y - 78.
