Question

3) (a-26)-(a+26); 4) (2x+3y)+(3x-2y).

Answer 1

Ответ:

Объяснение:

$(a-26)-(a+26)=a-26-a-26=-52$

$(2x+3y)+(3x-2y)=2x+3y+3x-2y=5x+y$

Answer 2

$\displaystyle \tt 3) \: (a-26)-(a+26)=a-26-a-26=a-a-26-26=-52\\4) \: (2x+3y)+(3x-2y)=2x+3y+3x-2y=2x+3x+3y-2y=5x+y$

Answer 3

Let's simplify the given expressions:

1. (a - 26) - (a + 26)

To simplify this expression, we can distribute the negative sign inside the parentheses:

(a - 26) - (a + 26) = a - 26 - a - 26

Next, we can combine like terms by adding or subtracting the coefficients of the variables:

a - a - 26 - 26 = -52

Therefore, (a - 26) - (a + 26) simplifies to -52.

2. (2x + 3y) + (3x - 2y)

To simplify this expression, we can combine like terms by adding the coefficients of the variables:

(2x + 3y) + (3x - 2y) = 2x + 3y + 3x - 2y

Next, we can rearrange the terms:

(2x + 3x) + (3y - 2y) = 5x + y

Therefore, (2x + 3y) + (3x - 2y) simplifies to 5x + y.
