Question

0,3(6-2y)=4,5-0,7(-9)​

Answer 1

Відповідь:

0,3*(6-2у)=4,5-0,7*(-9)

0,3*(6-2у)=4,5+6,3

1,8-0,6у=10,8

-0,6у=10,8-1,8

-0,6у=9

у=-15

или

0,3*(6-2у)=4,5-0,7*(-9)

0,3*(6-2у)=4,5+6,3

6-2у=10,8:0,3

-2у=36-6

-2у=30

у=-15

Answer 2

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

Step 1: Distribute the numbers inside the parentheses: 0.3 * 6 - 0.3 * 2y = 4.5 + 0.7 * 9

Step 2: Simplify the expressions: 1.8 - 0.6y = 4.5 + 6.3

Step 3: Combine like terms: -0.6y = 10.8

Step 4: Isolate y by dividing both sides by -0.6: y = 10.8 / -0.6

Step 5: Calculate the result: y = -18

So, the solution to the equation is y = -18.
