Question

6*(2х-3)+2*(4-3х)=5 8*(2а-6)=2*(4а+3)

Answer 1

Ответ:

1. 2,5

2. 6,75

Пошаговое объяснение:

раскрываем скобки:

12x-18+8-6x=5

переносим числа в 1 сторону, х в другую и приводим подобные

6x=15

x=15/6

x=2/5

2. алгоритм тот же

решение:

16a-48=8a+6

8a=54

a=54/8

a=6,75

Answer 2

To solve these equations, we'll need to isolate the variables (x and a) on one side of each equation. Let's solve each equation step by step:

1. Equation 1: 6(2x-3) + 2(4-3x) = 5**

Distribute the numbers inside the parentheses:

12x - 18 + 8 - 6x = 5

Combine like terms:

(12x - 6x) - 18 + 8 = 5

6x - 10 = 5

Add 10 to both sides:

6x = 15

Divide both sides by 6:

x = 15 / 6 x = 2.5

So, the solution for x is x = 2.5.

2. Equation 2: 8(2a-6) = 2(4a+3)**

Distribute the numbers inside the parentheses:

16a - 48 = 8a + 6

Subtract 8a from both sides:

16a - 8a - 48 = 6

8a - 48 = 6

Add 48 to both sides:

8a = 54

Divide both sides by 8:

a = 54 / 8 a = 6.75

So, the solution for a is a = 6.75.

To summarize:

• For the first equation, x = 2.5.
• For the second equation, a = 6.75.
