Question

A)-2x+3x-5x Б)2a-5-a+4

Answer 1

Ответ:

a) -2x + 3x - 5x = x - 5x = 4x

б) 2a - 5 -a + 4 = a - 1

Answer 2

Ответ:

-2x + 3x - 5x = x - 5x = 4x

2a - 5 -a + 4 = a - 1

Объяснение:

Answer 3

It seems like you've provided two expressions, labeled A) and B). Let's simplify these expressions:

A) -2x + 3x - 5x: Combine the x terms: -2x + 3x - 5x = (3 - 2 - 5)x = -4x

So, the simplified form of expression A) is -4x.

B) 2a - 5 - a + 4: Combine the constant terms and the 'a' terms separately: 2a - a = a -5 + 4 = -1

Now, the simplified expression B) becomes: 2a - 5 - a + 4 = a - 1

So, the simplified form of expression B) is a - 1.
