Question

X-3+6x=2•(2x+1)-3•(4-x)

Answer 1

X-3+6x=2(2x+1)-3(4x-3)
7x-3=4x+2-12+3x
7x-3=7x+10
-3≠10
Ответ: нет корней.

Answer 2

Let's solve the equation step by step:

X - 3 + 6x = 2(2x + 1) - 3(4 - x)

First, distribute the constants on the right side of the equation:

X - 3 + 6x = 4x + 2 - 12 + 3x

Now, combine like terms on both sides of the equation:

X + 6x - 3 = 4x + 2 - 12 + 3x

Combine like terms on each side:

7x - 3 = 7x - 10

Now, notice that you have 7x on both sides of the equation. To isolate x, subtract 7x from both sides:

7x - 7x - 3 = 7x - 7x - 10

This simplifies to:

-3 = -10

However, this equation has no solution because -3 is not equal to -10. In other words, there is no value of x that will make this equation true.
