3э+6э+78=1617

To solve the given equation, let's combine like terms first.

3э + 6э + 78 = 1617

Combining the coefficients of similar variables:

(3 + 6)э + 78 = 1617

9э + 78 = 1617

Now, let's isolate the variable э by subtracting 78 from both sides:

9э = 1617 - 78

9э = 1539

Dividing both sides by 9:

э = 1539 / 9

э = 171

Therefore, the value of э in the given equation is 171.
