Question

Solve for the proportion. x+2/5=6/15

Answer 1

`x = 0`

Explanation:

`x + (2)/(5) = (6)/(15)`

Simplify
`(6)/(15)` so that both fraction have the same denominator

`(6/3)/(15/3)`

Subtract
`(2)/(5)` from each side.

`x + (2)/(5) = (2)/(5) \\-(2)/(5) -(2)/(5) \\\\x = 0`

Answer 2

For this case we must solve the following proportion:

`\frac {x + 2} {5} = \frac {6} {15}`

Multiplying by 5 on both sides of the equation we have:

`x + 2 = \frac {6 * 5} {15}\\x + 2 = \frac {30} {15}\\x + 2 = 2`

Subtracting 2 from both sides of the equation:

`x = 2-2\\x = 0`

ANswer:

`x = 0`
