Answer 3

To solve the equation 0.3(2y - 11) = 0.2(y - 7) - 3.74, you can follow these steps:

1. Distribute the constants on the left side and the right side of the equation to eliminate the parentheses:

   0.6y - 3.3 = 0.2y - 1.4 - 3.74

2. Now, combine like terms on both sides of the equation. Start by subtracting 0.2y from both sides and adding 3.3 and 1.4 to both sides:

   0.6y - 0.2y = -3.74 + 3.3 + 1.4

3. Simplify both sides:

   0.4y = -3.74 + 3.3 + 1.4

4. Continue simplifying the right side:

   0.4y = -3.74 + 4.7

5. Add the values on the right side:

   0.4y = 0.96

6. Finally, divide both sides by 0.4 to isolate y:

   y = 0.96 / 0.4

7. Calculate the value of y:

   y = 2.4

So, the solution to the equation is y = 2.4.
