Question

4(0,3х-2)-5(0,4х-2,)=-2​

Answer 1

Відповідь:

5

Покрокове пояснення:

4(0,3x-2)-5(0,4x-2)=-2

1,2x-8-2x+10=-2

1,2x-2x=-2+8-10

-0,8x=-4

x=-4÷(-0,8)

x=5

Answer 2

To solve the given equation, let's simplify the expression step by step:

4(0,3х - 2) - 5(0,4х - 2) = -2

First, let's distribute the multiplication:

4 * 0,3х - 4 * 2 - 5 * 0,4х + 5 * 2 = -2

0,12х - 8 - 0,2х + 10 = -2

Next, combine like terms:

(0,12х - 0,2х) + (-8 + 10) = -2

0,12х - 0,2х + 2 = -2

Now, combine the x terms:

0,12х - 0,2х = -2 - 2

-0,08х = -4

To solve for x, divide both sides of the equation by -0,08:

x = (-4) / (-0,08)

x = 50

Therefore, the value of x that satisfies the equation is x = 50.
