Question

1 - x + 6 = 5 + 4x 2 - 13 - 3(x+1) 3 - 0,2(3x-5)-0,3(x-1)=4-5x

Answer 1

Х+6=5+4х
х-4х=5-6
-3х=-1
х=1/3

13-3(х+1)=4-5х
13-3х-3=4-5х
-3х+5х=-13-3
2х=-10
х=-5


0,2(3х-5)-0,3(х-1)=4-5х
0,6х-1-0,3х+0,3=4-5х
0,6х-0,3х+5х=1-0,3
0,8х=0,7
х=7/8

Answer 3

Let's solve each of these equations step by step:

1. $1 - x + 6 = 5 + 4x$

First, simplify both sides of the equation:

$1 + 6 - x = 5 + 4x$

Now, combine like terms on both sides:

$7 - x = 5 + 4x$

Next, add $x$ to both sides to isolate the $x$ terms on one side:

$7 = 5 + 5x$

Now, subtract 5 from both sides:

$7 - 5 = 5x$

$2 = 5x$

Finally, divide both sides by 5 to solve for $x$:

$x = \frac{2}{5}$

So, the solution to the first equation is $x = \frac{2}{5}$.

2. $2 - 13 - 3(x + 1)$

Start by distributing the -3 to both terms inside the parentheses:

$2 - 13 - 3x - 3$

Now, combine like terms:

$-11 - 3x$

So, the simplified form of the second equation is $-11 - 3x$.

3. $0.2(3x - 5) - 0.3(x - 1) = 4 - 5x$

First, distribute the constants on the left side of the equation:

$0.6x - 1 - 0.3x + 0.3 = 4 - 5x$

Now, combine like terms on both sides:

$0.6x - 0.3x - 1 + 0.3 = 4 - 5x$

$0.3x - 0.7 = 4 - 5x$

Next, add $5x$ to both sides to isolate the $x$ terms on one side:

$0.3x + 5x - 0.7 = 4$

Now, combine the $x$ terms:

$5.3x - 0.7 = 4$

Finally, add 0.7 to both sides:

$5.3x = 4 + 0.7$

$5.3x = 4.7$

Now, divide both sides by 5.3 to solve for $x$:

$x = \frac{4.7}{5.3}$

So, the solution to the third equation is $x = \frac{4.7}{5.3}$.

To summarize:

1. $x = \frac{2}{5}$
2. $-11 - 3x$
3. $x = \frac{4.7}{5.3}$
