Question

2(x)+2(x-3)=18 x-3 и x степень

Answer 1

Ответ:

Пошаговое объяснение:

$2^x +2^{x-3} = 18\\(2^3+1)*2^{x-3}=18\\9*2^{x-3}=18\\2^{x-3}=2^1\\x-3=1\\x=1+3\\x=4$

Answer 2

To solve the equation 2(x) + 2(x-3) = 18, we'll start by simplifying the equation and then isolating the variable x. Here are the steps:

1. Distribute the 2 on the left side of the equation: 2x + 2(x-3) = 18

2. Now, distribute the 2 inside the parentheses on the left side: 2x + 2x - 6 = 18

3. Combine like terms on the left side of the equation: 4x - 6 = 18

4. Add 6 to both sides of the equation to isolate 4x: 4x - 6 + 6 = 18 + 6 4x = 24

5. Finally, divide both sides by 4 to solve for x: 4x/4 = 24/4 x = 6

So, the solution to the equation is x = 6.
