Answer 1

Answer:
1.
`x=4`
2.
`x=(57)/(7)`
3.
`x=(27.7)/(11)`

Step-by-step explanation:

Given the following questions:


`12=3x`

`7x=57`

`11x=27.7`

In order to find the answers to these questions, we have to recognize that in order to isolate the variable we need to divide on both sides.

Question one:

`12=3x`

`(3x)/(3) =/3`

`12/3=4`

`x=4`

Question two:

`7x=57`

`(7x)/(7) =/7`

`57/7=8.14285714=(57)/(7)`

`x=(57)/(7)`

Question three:

`11x=27.7`

`(11x)/(11) /11`

`27.7/11=2.51818182=(27.7)/(11)`

`x=(27.7)/(11)`

Hope this helps.
