Question

Solve for x.
3/7x +1/4x =38

Answer 1

x=56

Explanation: simplify then isolate the variable

Answer 2

x = 56

Explanation:

`(3)/(7)` x +
`(1)/(4)` x = 38 The common denominator would be 28

`(12)/(28)` x +
`(7)/(28)` x =38

`(19)/(28)` x = 38 Multiply both sides by
`(28)/(19)`

`((28)/(19))`
`(19)/(28)` x =
`((28)/(19))`
`(38)/(1)` Cross cancel the 19 and 38.

x =
`((28)/(1))`
`(2)/(1)`

x = 56
