Question

Помогите и напишите пояснение 5-2x=11-7(x+2)

Answer 1

$5-2x=11-7(x+2), \\ 5-2x=11-7x-7\cdot2, \\ 7x-2x=11-14-5, \\ 5x=-8, \\ x=-8:5, \\ x=-1,6.$

Answer 2

5-2x=11-7x-14
5x=-8

x= - 8/5

Answer 3

I can help you solve this equation. Here are the steps:

- First, we need to apply the distributive property of multiplication over addition to the term 7(x+2). This means that we multiply 7 by both x and 2, and then add the results. We get 7x + 14. - Next, we simplify the equation by subtracting 14 from both sides. This gives us 5 - 2x = 11 - 7x - 14. - Then, we collect the terms with x on one side, and the constants on the other side. To do this, we add 2x to both sides, and then subtract 11 from both sides. We get 5 - 11 = -7x + 2x - 14. - Now, we simplify the equation by combining the like terms. We get -6 = -5x - 14. - Next, we add 14 to both sides to isolate the term with x. We get 8 = -5x. - Finally, we divide both sides by -5 to find the value of x. We get x = -8/5 or x = -1.6.

Therefore, the solution of the equation is x = -1.6. You can check this by plugging the value of x into the original equation and verifying that both sides are equal.
