Question

(0,4x-2)-(1½x+1)=2,8-4x​

Answer 1

0,4х-2-(3/2х+1)=14/5-4х
0,4-2-3/2х-1=14-4х
2/5х-3-3/2х=14/5-4х
-11/10х-3=14/5-4х
-11х-30=28-40х
-11х+40х=28+30
29х=58
х=58:29
х=2

Answer 2

Let's solve the equation step by step:

The given equation is: $0.4x - 2 - (1.5x + 1) = 2.8 - 4x$

First, distribute the negative sign through the parentheses on the left side: $0.4x - 2 - 1.5x - 1 = 2.8 - 4x$

Combine like terms on the left side: $-1.1x - 3 = 2.8 - 4x$

Add $1.1x$ to both sides to isolate the terms with $x$ on one side: $-3 = 2.8 - 2.9x$

Subtract $2.8$ from both sides: $-5.8 = -2.9x$

Now, divide both sides by $-2.9$ to solve for $x$: $x = \frac{-5.8}{-2.9} = 2$

So, the solution for the equation is $x = 2$.
