Question

1)5(x-1)+7 12(3x-1)-16(x+1)

Answer 1

Ответ:

x=1

Объяснение:

5(x-1)+7+12(3x0-1)-16(x+1)=5x-5+7+36x-12-16x-16

5x+36x-16x=16+12-7+5

25x=25

x=1

Answer 2

Let's simplify the given expressions step by step:

1. 5(x - 1) + 7:

To simplify this expression, we can distribute the 5 to both terms inside the parentheses:

5(x - 1) + 7 = 5 * x - 5 * 1 + 7 = 5x - 5 + 7 = 5x + 2

Therefore, the simplified expression is 5x + 2.

2. 12(3x - 1) - 16(x + 1):

Again, we distribute the values outside the parentheses:

12(3x - 1) - 16(x + 1) = 12 * 3x - 12 * 1 - 16 * x - 16 * 1 = 36x - 12 - 16x - 16

Now, we can combine like terms:

36x - 12 - 16x - 16 = (36x - 16x) + (-12 - 16) = 20x - 28

Therefore, the simplified expression is 20x - 28.
