Answer 2

Ответ:

Пошаговое объяснение:

a)7-3x-3+4x-10 = -6 + x = x - 6

б)3(3+x)+6*7x-13​ = 9 + 3x + 42x - 13 = 45x - 4

Answer 3

Let's simplify both expressions:

A) 7 - 3x - 3 + 4x - 10

Combine like terms:

7 - 3 - 10 + (-3x + 4x)

Now, simplify further:

(7 - 3 - 10) + (x)

Combine the numbers within the parentheses:

(-6) + (x)

So, the simplified expression A is:

x - 6

B) 3(3 + x) + 6 * 7x - 13

First, perform the operations inside the parentheses:

3(3 + x) = 9 + 3x

Now, rewrite the expression with the simplified portion:

(9 + 3x) + 6 * 7x - 13

Now, distribute the 6 to the 7x term:

(9 + 3x) + (42x) - 13

Combine like terms:

9 - 13 + 3x + 42x

Combine the numbers:

(-4) + (3x + 42x)

Combine the x terms:

(-4) + (45x)

So, the simplified expression B is:

45x - 4
