Question

X+2x=22. 3x+x=14. x+2x+3x=30

Answer 1

3х=22;4х=14;6х=30

х=7,(3) ; х=3,5. ; х=5

Answer 2

x+2x=22

3x=22

x=22/1÷3/1

x=22/1×1/3

x=22/3

x= 7 2/3

3x+x=14

4x=14

x=14/1÷4/1

x=14/1×1/4

x=7/2

x=3 1/2

x+2x+3x=30

6x=30

x=30÷6

x=5

Answer 3

Let's solve the equations step by step:

1. x + 2x = 22

Combining like terms, we have:

3x = 22

Dividing both sides by 3, we find:

x = 22/3

2. 3x + x = 14

Combining like terms, we have:

4x = 14

Dividing both sides by 4, we find:

x = 14/4

Simplifying:

x = 7/2

3. x + 2x + 3x = 30

Combining like terms, we have:

6x = 30

Dividing both sides by 6, we find:

x = 30/6

Simplifying:

x = 5

Therefore, the solutions to the equations are:

x = 22/3, x = 7/2, and x = 5.
