1)х+5х=1202)3х+х=163)3х+х=72помогите решить дам 25 баллов​

Answer 1

Решение:

1)х+5х=120

6х = 120

х = 120 : 6

х = 20

Ответ: 20.

2)3х+х=16

4х = 16

х = 16 : 4

х = 4

Ответ: 4.

3)3х+х=72

4х = 72

х = 72 : 4

х = 18

Ответ: 18.

Answer 2

$\displaystyle 1)x+5x=120\\6x=120\\x=20\\\\2)3x+x=16\\4x=16\\x=4\\\\3)3x+x=72\\4x=72\\x=18$

Answer 3

1) To solve the equation 1х + 5х = 120, we can combine like terms on the left side of the equation. Adding the coefficients of the x terms gives us 6х. Therefore, the equation becomes 6х = 120. To isolate the variable x, we can divide both sides of the equation by 6. This gives us:

6х/6 = 120/6 х = 20

So the solution to the equation 1х + 5х = 120 is х = 20.

2) For the equation 3х + х = 16, we can combine the x terms on the left side of the equation. Adding the coefficients of the x terms gives us 4х. Therefore, the equation becomes 4х = 16. To isolate the variable x, we can divide both sides of the equation by 4. This gives us:

4х/4 = 16/4 х = 4

So the solution to the equation 3х + х = 16 is х = 4.

3) Similarly, for the equation 3х + х = 7, we can combine the x terms on the left side of the equation. Adding the coefficients of the x terms gives us 4х. Therefore, the equation becomes 4х = 7. To isolate the variable x, we can divide both sides of the equation by 4. This gives us:

4х/4 = 7/4 х = 7/4

So the solution to the equation 3х + х = 7 is х = 7/4 or 1.75.
