Question

6x-3, 2=7x-3(2x-2,5)​

Answer 1

Ответ:

6x-3,2=7x-3(2x-2,5)

6x-3,2=7x-6x+7,5

5x=10,7

x=2,14

L=6.2,14-3,2=12,84-3,2=9,64

P=7.2,14-3(4,28-2,5)=14,98-3.1,78=14,98-5,34=9,64

L=P

Answer 2

To solve the equation 6x - 3(2) = 7x - 3(2x - 2.5), let's simplify both sides step by step:

6x - 3(2) = 7x - 3(2x - 2.5)

Start by evaluating the expression within parentheses on the right side:

6x - 3(2) = 7x - 3(2x) + 3(2.5)

Multiply the numbers within parentheses:

6x - 3(2) = 7x - 6x + 7.5

Now simplify both sides further:

6x - 6 = 7x - 6x + 7.5

Combine like terms:

6x - 6 = x + 7.5

Next, isolate the x term on one side by subtracting x from both sides:

6x - x - 6 = 7.5

Simplify:

5x - 6 = 7.5

To isolate x, add 6 to both sides:

5x - 6 + 6 = 7.5 + 6

Simplify:

5x = 13.5

Finally, divide both sides by 5 to solve for x:

5x/5 = 13.5/5

Simplify:

x = 2.7

So, the solution to the equation 6x - 3(2) = 7x - 3(2x - 2.5) is x = 2.7.
