Question

2,4+4(-0,1x+0,8)=1,7-5(0,3x-1)

Answer 1

2,4 + 4 * (-0,1х + 0,8) = 1,7 - 5 * (0,3х - 1)

2,4 - 0,4х + 3,2 = 1,7 - 1,5х + 5

- 0,4х + 1,5х = 1,7 + 5 - 2,4 - 3,2

1,1х = 1,1

х = 1,1 : 1,1

х = 1

=======================

Проверка:

2,4 + 4 * (-0,1 * 1 + 0,8) = 1,7 - 5 * (0,3 * 1 - 1)

2,4 + 4 * 0,7 = 1,7 - 5 * (-0,7)

2,4 + 2,8 = 1,7 + 3,5

5,2 = 5,2

Answer 2

To solve the equation:

2.4 + 4(-0.1x + 0.8) = 1.7 - 5(0.3x - 1)

You can start by simplifying the equation step by step. First, distribute the constants on both sides of the equation:

2.4 + (-0.4x + 3.2) = 1.7 - (1.5x - 5)

Now, simplify further by combining like terms on both sides:

2.4 - 0.4x + 3.2 = 1.7 - 1.5x + 5

Combine constants:

5.6 - 0.4x = 6.7 - 1.5x

Now, move the terms containing x to one side of the equation and constants to the other side. You can do this by adding 1.5x to both sides and subtracting 5.6 from both sides:

5.6 + 1.5x - 0.4x = 6.7 - 5.6

Now, simplify further:

1.1x = 1.1

Finally, solve for x by dividing both sides by 1.1:

x = 1.1 / 1.1

x = 1

So, the solution to the equation is x = 1.
