Question

1,8(1-2x)=-2(1,8x+3)+7,8 help me please!!​

Answer 1

Ответ:

x=0

Пошаговое объяснение:

1,8(1-2x)=-2(1,8x+3)+7,8

1,8-3.6x=-3,6x+(-6)+7,8

3.6x-3,6x=-1,8+(-6)+7,8

x=-7,8+7,8

x=0

Answer 2

To solve the equation 1.8(1 - 2x) = -2(1.8x + 3) + 7.8, follow these steps:

Step 1: Distribute the numbers on both sides of the equation.

On the left side: 1.8 * 1 - 1.8 * 2x = 1.8 - 3.6x

On the right side: -2 * 1.8x - 2 * 3 + 7.8 = -3.6x - 6 + 7.8 = -3.6x + 1.8

So, the equation becomes: 1.8 - 3.6x = -3.6x + 1.8

Step 2: Subtract 1.8 from both sides to eliminate the constant term: 1.8 - 3.6x - 1.8 = -3.6x + 1.8 - 1.8 -3.6x = -3.6x

Step 3: Notice that both sides of the equation are already equal. This means that the equation is true for all values of x. In other words, the equation has infinitely many solutions.

Therefore, the solution to the given equation is all real numbers (x can be any real number).
