Question

A ) -2,4x + 4,8 = -3,2x б) - 3,3x + 4,2 = -1,9x + 2,8

Answer 1

a ) -2,4x + 4,8 = -3,2x
-2,4+3,2=-4,8
0,8х=-4,8
х=-6

б) - 3,3x + 4,2 = -1,9x + 2,8
-3,3х+1,9х=2,8-4,2
-1,4х=-1,4
х=1

Answer 2

To solve these equations for $x$, you'll need to isolate the variable $x$ on one side of the equation. Let's solve each equation step by step:

a) $-2.4x + 4.8 = -3.2x$

First, let's get all the $x$ terms on one side of the equation:

$-2.4x + 3.2x = 4.8$

Now, combine the $x$ terms on the left side:

$-2.4x + 3.2x = 0.8x$

So, the equation becomes:

$0.8x = 4.8$

Now, we need to isolate $x$. To do that, divide both sides of the equation by $0.8$:

$\frac{0.8x}{0.8} = \frac{4.8}{0.8}$

$x = 6$

So, the solution to equation (a) is $x = 6$.

b) $-3.3x + 4.2 = -1.9x + 2.8$

First, let's get all the $x$ terms on one side of the equation:

$-3.3x + 1.9x = 2.8 - 4.2$

Now, combine the $x$ terms on the left side:

$-3.3x + 1.9x = -1.4x$

So, the equation becomes:

$-1.4x = -1.4$

Now, we need to isolate $x$. To do that, divide both sides of the equation by $-1.4$:

$\frac{-1.4x}{-1.4} = \frac{-1.4}{-1.4}$

$x = 1$

So, the solution to equation (b) is $x = 1$.

Therefore, the solutions are $x = 6$ for equation (a) and $x = 1$ for equation (b).
