For this case we have the following equation:

The steps used by Viktoriya to solve are:
Step 1:
Distributive property:

Step 2:
Combine similar terms:

Step 3:
Simplify:

Viktoriya's error is in the conclusion of the problem.
The equation has no solution, because:
<em>Left side ≠ right side
</em>
Answer:
Viktoriya's error is: the equation has infinitely many solutions.
The answer to that is 300%
Y= 25/4 or if you want it in decimal form it’s 6.25
Answer:
Step-by-step explanation:
3n+4<19
3n<19-4
3n<15
n<5

combining
(-∞,-16)U(16/9,5)
In order to simplify a fraction, we have to find a common factor in both numerator and denominator. So, let's start by factor the expressions completely: at the numerator we have

At the denominator we have

So, the fraction can be written as

You can see that there is a factor
in common, that can be simplified:
