Question

2x + 1 + 5(x - 2) = -4(3-x) + 1.​

Answer 1

Ответ:

2x + 1 + 5(x - 2) = -4(3-x) + 1.​

2х + 5х -10 = -12 + 4х

7х - 10 = -12 + 4х

7х - 4х = -12 +10

3х = -2

х = -2/3

Answer 2

Let's solve the given equation step by step:

2x + 1 + 5(x - 2) = -4(3 - x) + 1

First, we distribute the 5 and -4 to their respective terms:

2x + 1 + 5x - 10 = -12 + 4x + 1

Next, we combine like terms on both sides of the equation:

7x - 9 = 4x - 11

To isolate the x terms on one side and the constant terms on the other side, we can subtract 4x from both sides and add 9 to both sides:

7x - 4x = -11 + 9

Simplifying further:

3x = -2

Finally, to solve for x, we divide both sides by 3:

x = -2/3

Therefore, the solution to the equation is x = -2/3.
