Question

0,2(5y - 2) = 0,3(2y – 1) – 0,9

Answer 1

0,2(5y - 2) = 0,3(2y – 1) – 0,9

y-0,4=0,6y-0,3-0,9

y-0,6y=-0,3-0,9+0,4

0,4y=-0,8

y=-2

Answer 2

To solve the equation 0.2(5y - 2) = 0.3(2y - 1) - 0.9, we can follow these steps:

1. Distribute the decimal coefficients: 1y - 0.4 = 0.6y - 0.3 - 0.9

2. Combine like terms: 1y - 0.4 = 0.6y - 1.2

3. Simplify the equation by moving all terms involving y to one side and constant terms to the other side: 1y - 0.6y = -1.2 + 0.4

4. Combine like terms: 0.4y = -0.8

5. Divide both sides of the equation by 0.4 to solve for y: y = -0.8 / 0.4

6. Calculate the result: y = -2

Therefore, the solution to the equation is y = -2.
