Question

6x-25=155 42:(10+x)=3

Answer 1

Ответ:

6x=155+25

6x=180

x=180/6

x=30

42:(10+x)=3

10+x=42:3

10+x=14

x=14-10

x=4

Answer 2

Ответ:

1. х = 30

2. х = 4

Пошаговое объяснение:

1. 6x - 25 = 155

6х = 155 + 25

6х = 180

х = 180/6

х = 30

2. 42 : (10 + x) = 3

х = 42 : 3 - 10

х = 4

Answer 3

To solve these equations:

1. 6x - 25 = 155

First, add 25 to both sides of the equation to isolate the term with x:

6x - 25 + 25 = 155 + 25 6x = 180

Now, divide both sides by 6 to solve for x:

6x/6 = 180/6 x = 30

So, the solution to the first equation is x = 30.

2. 42 / (10 + x) = 3

First, multiply both sides of the equation by (10 + x) to get rid of the fraction:

42 = 3 * (10 + x)

Now, distribute the 3 on the right side:

42 = 30 + 3x

Next, subtract 30 from both sides of the equation to isolate the term with x:

42 - 30 = 30 - 30 + 3x 12 = 3x

Now, divide both sides by 3 to solve for x:

12 / 3 = 3x / 3 4 = x

So, the solution to the second equation is x = 4.
