Question

0,3*(8-3y)=3,2-0,8(y-7) решение)

Answer 1

0,3*(8-3y)=3,2-0,8(y-7) 
2,4-3,2-5,6=0,9y-0,8y 
2,4 -8,8=0,1y 
-6,4=0,1y 
y=-6,4:0,1 
y=-6,4

Answer 2

To solve the equation 0.3 * (8 - 3y) = 3.2 - 0.8 * (y - 7), follow these steps:

Step 1: Distribute the multiplication on both sides of the equation.

0.3 * 8 - 0.3 * 3y = 3.2 - 0.8y + 0.8 * 7

Step 2: Simplify both sides of the equation.

2.4 - 0.3y = 3.2 - 0.8y + 5.6

Step 3: Move all the terms containing 'y' to one side of the equation and the constant terms to the other side.

-0.3y + 0.8y = 5.6 + 3.2 - 2.4

Step 4: Combine the 'y' terms and simplify the constant terms.

0.5y = 6.4

Step 5: Isolate 'y' by dividing both sides by 0.5.

y = 6.4 / 0.5

Step 6: Calculate the value of 'y'.

y = 12.8

So, the solution to the equation is y = 12.8.
