X+2/3=9/10 what does x equal

PtichkaEL [24]

Answer:

x = 7/30

Step-by-step explanation:

Identify the LCD; it is 30. 30 is the smallest number divisible by both 3 and 10.

Then we have:

(30/30)x + 20/30 = 27/30.

Clearing out the fractions, we get:

30x + 20 = 27, or 30x = 7

Dividing both sides of this result by 30 yields x = 7/30.
