Question

Which equations have the same value of x as 3/5(30x−15)=72 ? Select three options. Responses 18x−15=72 18 x minus 15 is equal to 72 50x−25=72 50 x minus 25 is equal to 72 18x−9=72 18 x minus 9 is equal to 72 3(6x−3)=72 3 times (6 x minus 3) is equal to 72 x=4.5

Answer 1

The equations which will have the same value of x as the given equation is:

`18x-9=72`

`3(6x-3)=72`

`x=4.5`

Step-by-step explanation:

We are given a equation in terms of the variable x as follows:

`(3)/(5) (30x-15)=72`

Hence, we have:

`(3)/(5)*30x-(3)/(5) *15=72`

`18x-9=72`

Now, on taking common 3 in the left hand side of the equation we have:

`3(6x-3)=72`

`\text{i.e}`

`6x-3=(72)/(3)`

`6x-3=24`

`6x=24+3`

`6x=27`

`x=(27)/(6)`

`x=(9)/(2)`

`x=4.5`
