6•y-4•y+5•y-19=9•2-2

Let's solve the equation step by step.

The equation given is:

\[ 6y - 4y + 5y - 19 = 9 \cdot 2 - 2 \]

First, simplify both sides of the equation.

On the left side:

\[ 6y - 4y + 5y = (6 - 4 + 5)y = 7y \]

So, the left side simplifies to:

\[ 7y - 19 \]

Now, simplify the right side:

\[ 9 \cdot 2 - 2 = 18 - 2 = 16 \]

Now, we can rewrite the equation:

\[ 7y - 19 = 16 \]

Next, add 19 to both sides:

\[ 7y - 19 + 19 = 16 + 19 \]

This simplifies to:

\[ 7y = 35 \]

Finally, divide both sides by 7:

\[ y = \frac{35}{7} \]

So:

\[ y = 5 \]

The solution to the equation is \( y = 5 \).
