Пошаговое объяснение:

3х-15=х+3

3х-х=3+15

2х=18

х=9

2(х+3)=х+13

2х+6=х+13

2х-х=13-6

х=7

3(х-2)=4х+3

3х-6=4х+3

3х-4х=3+6

-х=9

х=-9

Answer 3

It seems like you have three different equations. Let's solve each of them one by one.

1. 3x - 15 = x + 32 To solve this equation, we need to isolate the variable x. First, we can simplify the equation by moving the x on the right side to the left side and the constant terms to the right side:

3x - x = 32 + 15

Now, combine like terms:

2x = 47

Next, divide both sides by 2 to solve for x:

2x/2 = 47/2

x = 47/2

So, the solution to the first equation is x = 23.5.

2. 32(x + 3) = x + 133 Let's simplify this equation by distributing the 32 on the left side:

32x + 96 = x + 133

Now, move the constant terms to the other side of the equation:

32x - x = 133 - 96

Combine like terms:

31x = 37

Now, divide both sides by 31 to solve for x:

31x/31 = 37/31

x = 37/31

So, the solution to the second equation is x = 37/31.

3. 133(x - 2) = 4x + 3 Similarly, let's simplify this equation by distributing the 133 on the left side:

133x - 266 = 4x + 3

Now, move the constant terms to the other side of the equation:

133x - 4x = 3 + 266

Combine like terms:

129x = 269

Now, divide both sides by 129 to solve for x:

129x/129 = 269/129

x = 269/129

You can simplify this fraction by finding the greatest common divisor (GCD) of 269 and 129, which is 1:

x = (269/1) / (129/1) = 269/129

So, the solution to the third equation is x = 269/129.

In summary, the solutions to the three equations are:

1. x = 23.5
2. x = 37/31
3. x = 269/129
