Question

0,3•(6-2y)=4,5-0,7•(y+9)​

Answer 1

0,3•6-0,3•2y=4,5-0,7y-0,7•9

1,8-0,6y=4,5-0,7y-6,3

0,6y+0,7y=4,5-6,3-1,8

y=36

Answer 2

To solve the equation 0.3 * (6 - 2y) = 4.5 - 0.7 * (y + 9), follow these steps:

1. Distribute the constants on both sides of the equation and simplify:

   0.3 * 6 - 0.3 * 2y = 4.5 - 0.7 * y - 0.7 * 9

2. Perform the multiplications:

   1.8 - 0.6y = 4.5 - 0.7y - 6.3

3. Combine like terms by moving the variables (y terms) to one side of the equation and constants to the other side:

   -0.6y + 0.7y = 4.5 - 6.3 - 1.8

4. Combine the y terms:

   0.1y = -3.6

5. Finally, solve for y by dividing both sides by 0.1:

   y = -3.6 / 0.1 y = -36

So, the solution to the equation is y = -36.
