Question

0.25(3x-4)=0.45(4x-2)-2.2​

Answer 1

Ответ:

0,75x-1=1,8-0,9-2,2

0,75-1,8x=-0,9-2,2+1

-1,05=-2,1

x-2,1/1,05

x=2

Answer 2

To solve the given equation, let's start by distributing the constants on both sides of the equation and simplifying:

$0.25(3x - 4) = 0.45(4x - 2) - 2.2$

Expand the equation:

$0.75x - 1 = 1.8x - 0.9 - 2.2$

Combine like terms:

$0.75x - 1 = 1.8x - 3.1$

Now, let's isolate the variable $x$. Move $0.75x$ to the right side by subtracting $0.75x$ from both sides:

$-1 = 1.05x - 3.1$

Add $3.1$ to both sides:

$2.1 = 1.05x$

Finally, divide by $1.05$ to solve for $x$:

$x = \frac{2.1}{1.05} = 2$

So, the solution to the given equation is $x = 2$.
