Question

Sole the proportion

Answer 1

11/6 or 1.8333333333

Explanation:

`(2x + 1)/(6)` =
`(7)/(9)`

Cross Multiply:

7 x 6 = 42

9 (2x+1)

42 = 9(2x+1)

42 = 18x + 9

Then, isolate the variable. In order to do so, subtract 9 from both sides.

33 = 18x

Now, divide by 18 (to find x)

33/18 =

1.8333333 or 11/6
